These guys are fantastic! The technicians are great and the service is great. Whether you're getting your car ready for the race track, getting repairs, or even just routine maintenance, these are the guys to go to! read more

Greg and the team at Perfromance Dynamic were professional, thorough, and precise in their diagnostics. Highly recommend this place for BMW enthusiasts with performance oriented cars. read more

Went there to get High Press Fuel Pump replaced. There prices are 1/3 of what BMW charges and also comes with warranty. When they order parts, they send you tracking number so you don't have to keep calling to ask if the parts are there. These guys know what they are doing and started working on the car right away even though it was burning hot. (I had to go somewhere). So I was in an out in an hour with a new HPFP when BMW wanted to keep the car all day. read more

I usually don't like to leave negative reviews for small business owners but this had to be said. This is long over due but I would avoid Greg and his shop at all cost. All the positive reviews are from his friends so I would not trust most of them. I went in for rod bearings and a bunch of other maintenance while my car was in there. Greg had the audacity to charge me and continue to work on my car and it's other maintenances when he told me it needed a new motor AFTER he completed the rod bearings. Like wth if it's not fixable and it needs a new motor why would you continue to perform the other maintenances and charge the customer for it. Very unprofessional, Greg misdiagnosed my car and said he was able to fix it. 2.5k later spent on rod bearings and then he told me that my car needed a new motor. When I brought it in it was my main concern that it would need a new motor and Greg assured me it was just the rod bearings and then after he replaced it Greg realized it was not salvageable and then he twisted his words and told me that he said that this was a possibility when he ASSURED from the start, it was fixable. On top of that when I went to pick up my car, things in the engine bay weren't completely put back together and Greg blamed his colleagues for the mistake. It seemed like it was a rushed job even though Greg had my car for ~2 months+, It has me question the overall quality of work. In the end I cut my losses and paid for a broken car and will avoid his shop at all cost, if I had seen the other one star review that Greg received about his work I would have avoided this place from the start. There are much better priced, quality, shops in the Bay Area then at Performance Dynamic. read more

Love these homies at Performance Dynamic. They're super chill and straight forward with you and they help you out to the best of their ability. I've been going to this place for about a year and half now. Greg first did my rod bearings and plenty other stuff every since. Super reliable and don't hesitate to give wyatt a call. read more

Very happy with my experience here at Performance Dynamic. I had my BMW 2009 E90 M3's rod bearings and motor mounts replaced here. Not only was the price really amazing (much more reasonable than the similarly named Performance *Technic* in Fremont), but Greg also provided exceptional customer service completing the job very quickly, and super helpful in explaining every step of the way. He is a true BMW enthusiast, and really knows his way around these cars. I would certainly recommend him to my friends and family, and will be bringing my car back to him for any follow-up work. read more

Greg and his staff are the only ones I trust with my M4. I am the type of person that can't leave anything "stock" and Greg has helped me build my car into an absolute beast. Pure Turbos,CSF intercooler, Crankhub,downpipes, chargepipes,heat exchanger, and recently port injection. This car puts a smile on my face every time I drive it. More importantly, the car has been 100% reliable. Greg is an honest guy that never tries to sell me unnecessary work. I'm definitely a customer for life! read more

Greg is such a humble owner, super knowledgeable about the bmw platform, doesn't try to sell you anything. He got into cars and his current job because he came from being screwed over by mechanics all the time-- now really shows how a great mechanic can bring so much value. He is sociable guy. I came here for a break in oil change for my 23 supra. Was super quick. Looking forward to coming here again in the future. read more

5**** TRUSTED TECH** Greg and his team are extremely knowledgeable and their to help you diagnose and fix your car.

I've been to Performance Dynamics now multiple times with my car to get different things done and I can say that they are the #1 shop in Bay Area if you are looking for really high caliber BMW expertise. Greg and the team are incredible - highly recommended! read more

Wanted to take the time and express how extremely satisfied with Greg's work. My son's car was towed in from another shop, for a no start situation. Greg with in minutes of dropping off the car calls me, to say "car is running". I was completely shocked. He further inspected the car, and found a number of things that I just finish paying for about a 1000 miles before. I don't want to mention the shops name! He corrected everything, and did an upgraded clutch and flywheel. If you are looking for honest, knowledgeable, and a great value....please visit Greg first! read more

BEST IN THE WEST! Performance Dynamic is by far the best shop I've ever been to. In terms of quality service, customer relations, and overall price, there is NO shop that can compare. Greg, who is the lead mechanic you'll be dealing with, is one of the nicest guys I've ever met and won't hesitate to take time out of his busy schedule to answer any questions you have for him or your car. Cars : - 2008 E90 335i FBO 85k miles - *Upcoming* 2000 E39 540i manual 190k miles E90 : I first took my E90 to Performance Dynamic for a Walnut Blasting and was shocked they quoted me at HALF of what my previous shop did. Greg sent me messages through their ShopMonkey platform in real time to let me know how my car was doing as well as sent several pictures of each intake valve before and after the Walnut Blasting. Not only were the Before and After pictures like night and day, but so was the performance of my car. I also had a list of things I stored in my notes on my phone about possible mods and where I should take the platform at its current state. He was more than happy to go over all the questions I had in terms of tuning, modifications, and preventative maintenance. I also had purchased a couple small parts off BMS I had asked him to install, and he was able to walk me through the process step by step with my engine bay open as he performed the installations, which to me is PRICELESS. He only charged me for the Walnut Blasting and said it's his pleasure to be able to teach and inform people on what to do with their cars. This was when I knew Greg was a true stand up guy that was deeply passionate about his work and how he conducted his business. This gave me a lot of respect not only for Greg but for Performance Dynamic as a whole, and I knew right then that I'd be a CUSTOMER FOR LIFE. Upcoming Work : I'm currently in the process of purchasing a E39 540i as a project car on the side and will be taking it into Greg and his team to do a full diagnostic check before I decide to pull the trigger or not. I'm also in the process of upgrading my suspension on my E90 due to a few leaky struts I have and Greg recommended a set of ST XTA's that were actually a lot less than the options I was considering before, and even more suitable for where I want to take my E90. No matter what I always feel like Greg is on my side, always giving me the best advice on top products without having to waste money on anything extra. To try and wrap this up, If you have a BMW and live anywhere near the Bay Area (yeah even SoCal), you need to stop throwing away your money at other shops and come to Performance Dynamic. The overall experience, knowledge shared, and quality of work is PRICELESS and can't be found anywhere else. If you're lucky enough to be about 30 minutes away like I am, then you will have the most trustworthy, helpful, and passionate shop to service your car for LIFE. Thank You Greg and Zach for always giving 110% in everything you do. read more

Wyatt and staff are BMW experts and take the time to listen to their customers and provide excellent service unlike what I experience at the Mountain View BMW dealership where I feel like they just care about collecting money. I brought my car in to diagnose a check engine light and creaking noise. They pinpointed the 2 issues with accuracy and even pointed out another additional leak. I am a mid-level skilled do-it-yourself person, so I fixed it myself, but I wouldn't have been able to diagnose as well as them. In fact, I was about to buy the incorrect part, but they told me the correct part number through their report. Another small detail, they even put up my windshield shade up after their work, who does that? Only the best. I will be bringing my BMW to this shop from now on. read more

Greg and his team are amazing. I had problems with my hardtop bmw and Greg fixed it within 2 hours for a very good price. I will definitely be coming back here for future issues as they are fast, nice, super reasonable, and definitely know what they are doing. Thanks again Performance Dynamics for the great experience and thank you Greg. read more

Gregory helped me with my M4 and gave me lots of valuable information in terms of warranty and common issues with it. He's knowledgeable on M3/M4, willing to work with customer, highly recommend Gregory for any bmw service especially M cars! read more

This shop is awesome! I have a 2008 bmw 335i. One day coming back from work my Hks Blow off valve flew off the chargepipe because the snap ring holding it in became loose. It wasn't the first time but I wasn't able to install it back myself the ring wouldn't go under the groove no matter what I did. So I decided to reach out to him and ask him for some help he told me to stop by the shop. Once I arrived at the shop, I let him know what the problem was and he took a look at it after battling it out with the ring for a few minutes it finally went under the groove. He's also a really cool and nice person. The customer service was awesome will be back to install my Downpipes and do maintenance. I highly recommend him you also won't find better prices with that quality of work and knowledge. Overall 10/10 read more

Performance Dynamic - Thanks for the quick fix. - Auto Repair Near Me - Mountain View, California

Greg is the best. Recommended to me by multiple friends and I wasn't disappointed. He installed a SPEC Stage 3+ clutch and billet aluminum single mass flywheel for me. He got it done in 1 day and when I was having issues with it, he took it all back apart again to check every single component right then and there. He goes on test drives with you and won't give up on an issue until it's working the way it's supposed to. I will 100% always trust Greg at Performance Dynamics with my 135i. read more

Greg is the guy to go for anything BMW related. He works on every car just like they're his own. I had him done a lot of things on almost every BMW I owned and I will never stop going to him! His prices are also very reasonable. read more

1st off I'd like to say thank you to performance dynamic and the whole team, My bF schedule me an appt to have my 2015 428i in to get a coolant flush and a couple other minor stuff that needed attention. They were very quick and professional in communicating and made sure everything was as expect, tbh they actually went above my expectations and made sure my car was ready to go, prior to me going in, i noticed my front tire was low and I didn't think much of it beside just waiting when I get home and having my BF do it, but they noticed it and went out their way and added air to my tire. They truly do care about their customers. From here on out I will only be bring my cars to Performance Dynamic. Kudos to Zack for all his help, we appreciate you! read more

Greg is as honest and hardworking as they come. He was my go to technician at Mt. View BMW and I'm glad he's finally opened his own shop so that he can expand his services and customer base. There have been numerous times Greg has helped me solve a problem with my car with relative ease and decisiveness. I look forward to bringing my car back any time I have an issue or just want to install some upgrades or get an oil change. Highly trained and professional environment and a small business owner that treats every customers car as if it were his own! read more

My most amazing shop experience was with Greg and Zach. I've visited many acclaimed bimmer shops up and down the bay, but I can say with confidence that these two are the best. Both of them have such extensively knowledge in their specialty and made sure that I could understand exactly what was being done to my car the whole process. They are both super easy going people with a huge passion for what they do and the service they provide. YOU. WILL. NOT. BE. DISAPPOINTED. Making an appointment was also super simple by submitting a work order on their website. They are also very responsive to those as well. read more

Greg is THE best! He is so knowledgeable, honest, and professional. Took my X3 in for a reoccurring check engine light due to misfires. After a year long struggle, spending lots of $$$, and going to 3 different shops plus the dealership, no one could figure it out. Greg was able to diagnose the issue immediately and ordered the parts and installed them the very next morning. He even spent extra time explaining the root cause (incorrect parts previously used) and providing maintenance tips to avoid future problems. If you own a BMW, this is THE shop to go to. Highly recommended. Greg has the expertise, passion, and specialized tools and equipment needed to provide accurate diagnostics and quality workmanship. read more

Greg is a great mechanic with prior experience from BMW Mountain View. The prices he offers are very reasonable and he provides valuable advise. I got my BMW's oil filter gasket and valve cover gasket replaced here on the same day. Will work with him again in the future. read more

The absolute best shop to take your car if you have anything wrong or even want some things done. My water to air heat exchanger got a hole in it and was leaking, I called the folks up and told them my issue. Within an hour of dropping my car off they told me what needed to be replaced and how much it would be. They recommend an upgraded heat exchanger that has a guard for rocks so I'd never have that issue again. My latest experience was installing some lowering springs. I asked for a recommendation and within the next hour my parts were ordered and I got a great installation. They took good care of my car and did a thorough check to make sure the car was in good working order before I left the shop. Along with getting fantastic service here I was able to chit chat with the folks here for another half hour and they gave me some recommendations on what I should do next to get to the power level that I want in the car. From the customer service, the speed the work was done, and to the attention of detail that my car was given they earned a loyal customer. read more

Greg's honest and fair appraisal of my vehicle was instrumental in helping me decide whether to repair or trade. Greg talked me through everything he found with the car, walked through the options with me and was generous with his time as I asked question after question. I was looking for someone trustworthy to take care of my BMW and I lucked out in contacting Performance Dynamic. Anyone with a BMW should have this shop at the top of their list. read more

I brought my Porsche 996 in for a replacement of the radiators and the technician that worked on my car was amazing! Kyle had great attention to detail and even went above and beyond in cleaning out debris that had gotten into the bumper areas the were clogging the airflow of the previous radiators. I really do recommend bringing ANY vehicle you have to Performance Dynamic, but if you do bring your Porsche, Kyle is sure to spend that extra amount of time to put those little finishing touches on everything he does. read more

Greg is the man.. thank you for great service and advise. You have earned customer for life! Keep doing guys and see you soon!

I have been going to Greg for many years and he's serviced several of my BMW's with N54 and N55 engines. Greg is a great guy and definitely knows his sh#t ! He has years of experience with BMW's and from what I understand gained some of his experience working at Dinan. He is a perfectionist and understands how anal BMW owners can be because he's the same way :-) Because he has so much experience, he usually already knows the problem or doesn't waste hours trying to troubleshoot it like some of these other shops. He and his team are very knowledgeable and honest which is why a drive a hour away to take my cars to him. I definitely trust these guys for general and major BMW repairs to all out performance mods . I would definitely recommend these guys ! read more

After buying a 135i I wanted to get my valves cleaned from carbon buildup. Greg was priced very competitively, and generously made me aware of some other small things going on within the car. He has a booking software that kept me aware of updates, and didn't mind answering any of my questions. I tried contacting him on a Saturday, knowing he probably won't get back to me until Monday, and he called me back on the same day. Greg tells it to you straight, and I appreciate that. Give him a shot. read more

Having been previously screwed over by a front-yard indy mechanic I knew I wanted to only rely on a shop. As a business, they have a reputation to make and to keep. I am so glad to have found Greg through the local BMW car community. Not only is he BMW trained, worked at a BMW dealership, and on high performance vehicles at Dinan, but the man has an N54 engine tattooed on the entire length of his arm. He is definitely dedicated to his craft. Greg was able to help me get back on the road after a failed starter, tracing electrical gremlins to my bad OBD cable, gasket replacements and fixing my previous indy mechanics "work", all while installing some upgrades along the way. Later I found out that whener my previous indy mechanic would mess up a job, he would call Greg and ask for help. It's a small world afterall, and I'm glad to have found a new home for my car. read more

I was in the market for a BMW E46 M3 6spd coupe in Imola red late 2019. Couldn't find anything deserving here locally, so I made the leap and purchased what I was looking for in another state. Couldn't be happier. My M3 is not a daily driver. Meant for smiles per gallon only. Fast forward 6 months later, I noticed a clunk like sound coming from the rear of the vehicle. Many Sunday morning cruises later, the clunking was progressing. I called Greg at performance dynamic regarding my issue. He stated he had a positive idea what it is, but still insisted on having me come in for confirmation and estimate. Upon arrival, he inspected the vehicle carefully, cut no corners during overview, in a way that he was inspecting the vehicle as if he was going to purchase it for himself. As mentioned, he confirmed the problem and what was needed to fix it, along with a written estimate already prepared. He gave me two options for repair. Of course one option was more expensive than the other. He insisted on the less costly option and he did not once try to upsale me. He actually insisted on the lesser option to be honest. We made an appointment which was within a few days away from initial inspection. The repair was complete and vehicle was ready for pickup the next business day. I couldn't be happier. No more clunking. Also needed other minor issued address, which he did at no charge. I didn't decide to have my vehicle worked on at Performance dynamic because Greg has experience with BMW's and came highly recommended, or because he's a mutual friend and I should support the fast growning shop, or the fact he was the cheapest estimate around. I chose performance dynamic because being honest and trustworthy goes along way with me. Finding a shop that won't leave your bank account crying is hard to come by. I no longer have that issue. Greg meant all my expectations and some. This was my first visit into Greg's shop and it won't be the last. Thank you again.....my friend! read more

Recently, my e92 335i Bimmer's Sport shifting lever malfunctioned. I was only able to upshift to 3rd gear manually using the shift lever although steering paddle shifter still works. After extensive research, I concluded that the problem is caused by snapped wiring harness in the shifter assembly. It appears that, due to a poor design by BMW, there is a tight pivotal angle in the shifter assembly which causes the wire to snap, a well-known issue experienced by many e90 generation owners. I spoke to local BMW dealer and independent BMW shops about the repair. Unfortunately, they will only replace with brand new shifter at a great cost to me. Fortunately, I found Performance Dynamics in Santa Clara through a referral. The shop owner, Greg, although young but seems to be knowledgable about BMW cars. Furthermore, he is an avid Bimmer enthusiast and currently owns an e92 M3 himself (he showed me the performance tuning & upgrade he did on his Bimmer). After chatting, I learned that he was with BMW of Mountain View before opening his shop. Eventually, I asked him to patch the snapped wiring instead of replacing the entire shifter assembly. Surprisingly, it only took him an hour to complete the repair. Now, my shifter works just as fine as before. Later, I also asked Greg to grease the front brake pads to eliminate an annoying pad shifting noise. In the end, the labor cost he charged was very reasonable. But most importantly, he did a great job and saved me a boatload of money if I had gone to dealers or other shops. In the following week, per his recommendation, I also asked him to reflash my other e92 M3's DCT with the latest M3 GTS firmware. Now I have a working Sport shifting e92 335i as my daily drive and a much more responsive DCT for my weekend M3, with which both are done professionally in a cost-effective manner, to say the least. Finally, I asked Greg to provide me with various tuning options available for both Bimmers. I plan to leverage his expertise to maximize their performance potential in the future! With that said, I highly recommend Greg and his shop for any serious bimmerphiles. read more

I just recently sold my 2011BMW 335is. It was full bolt on e85 tuned. Greg was my man to go to whenever I needed something done to the car. THIS IS THE ONE AND ONLY GUY YOU WANT WORKING IN YOUR CAR! I swear the man treats you car like his own and that what we are lacking here in the Bay Area. Very humble down to earth guy who is super knowledgable and has some of the best rates in the Bay, literally the only guy I trust with my car. Before I sold my car he inspected everything and told me what to expect for upcoming maintenence. Hands down recommend this guys for everything and anything BMW related read more

As for most BMWs, I was in need of a Walnut Blasting service as my car was not performing up to par. Through several phone calls and review-reading, I found Performance Dynamic, which is fully run by the great man, Greg. He knew basically anything one could know about these N54 engines and provided the best customer service anyone could dream of. He worked very efficiently, used mats to protect the paint of the car, and made sure to explain everything he was doing. He even dealt with the many questions I had and I couldn't think of a question he didn't know the answer to. His work is outstanding and his customer service is pure; Greg performs amazing work at a very competitive price and gives me peace of mind knowing that whenever my car acts up, Greg will put it in check. Whether it be regular maintenance or installing aesthetic or performance mods, there is no other place to go than Greg at Performance Dynamic. read more

I want to thank Greg for fixing all the issues I have on my e92 m3. I had over 20 check engine lights that nobody couldn't figure out the issue. He was able to diagnose and fix all the issues on my car that other shops couldn't do. The experience I had here doesn't come close to any shops I've been to in the past. If only I can give them ten Stars! Very knowledgeable and very honest. Hands down to the best customer service experience. I will always be taking my cars here and will be supporting this business. If you guys are looking for the best shop in the Bay Area, this is the one. Thank you again. read more
