It's freaking impossible to find a qualified HP tuner in the Bay Area. After searching for nearly a month I was able to stumble across Newtech Performance on the ol interweb I got in contact with Nick "the Tuner" who has been Dyno tuning cars for years. I made an appointment with for him Dyno tune my car "no you can't just drop in and expect him to tune your car" When I brought my car in I spoke with Nick and told him the modifications I performed on my car. Nick is super nice but more importantly knows what the heck he's doing "super smart and has a wealth of knowledge. After tuning my car, Nick told me that the ECM had way to much timing programed into it "29 degrees " and would have been detrimental to my new engine. Overall my car drives smoother now and my gas mileage has improved. Rear wheel HP came in at 434 @ 5700rpm 414 ft lbs @ 5250 read more

See all

Nick has tuned several of our LS1 Camaros for SCCA racing. He's always thorough and professional...and gets amazing results. We've won a regional championship, won races and set lap records with his tunes. Thanks, Nick. 100% recommended. read more

Very happy with the Tune Nick was able to do for my SS; The Whipple tune that came with the kit was horrendous and the engine was pinging at anything above half throttle. Newtech was highly recommended amongst the SS forum and Norcal Holden FB group. Nick responded promptly to my email and was able to take care of my car on short notice. Definately recommending this shop to other SS owners read more

Tried getting my car tuned but, they're not responsive. Doesn't reply back to messages in a fashionable manner, no clue on what's going on.

Nick got me in same day I called about my 68 GTO LS swap. I needed a tune and he saved me. Car drives great and he recommended some ideas for better dyno numbers. Will totally be coming back. Thanks Nick read more

Car was Tuned by Nick and it is running very rich, Gear Shift Points are off. Nothing was done. He took the tune off the shelf and loaded instead of actually dialing everything in. I brought low miles CTSV for a basic bold ons. Josh does amazing work installing but this tuner defiantly has no idea what's his doing or bothers to drive and test the vehicles after works. I took it to Matt from GP and he had to fix a never ending list what was not even done. Car ran like shit after his tune. I left voice mails calls and no over even bothered to call back. Josh's reply from JRG was you probably broke something without even offering to take the car in. Once again installation work was perfect but not the place you want to bring your LS cars too. No one gives a shit here. read more

I took my 2009 Silverado 4x4 LT Crew Cab to Nick after I purchased it. The previous owner had paid for a lot of mods to the truck without tuning it. Prior to the tune, the over-sized 34" tires and transmission where out of sync. This was leading to some fairly bad MPG and hard accelerations. I want to say from the start that I did not request a "performance" tune. I wanted a tune for towing/hauling and for 87 octane usage. Nick worked several hours tuning the truck. He managed to correct the very lean fuel usage and saved my knock sensors. The transmission is now synced to the tires as well and driving feels great. The truck no longer whines, the MPG has increased slightly, and towing/hauling feels stronger in all gears. I am glad I had this service done to my vehicle. read more

Took my '14 pro charged vette in with no appointment and he handled the tune same day. He said give him a couple hours, I was expecting him to have the car over night as I had no appointment but he dyno'd/tuned it in right around 1-1/2 or 2 hours ish and fixed my pretty large power loss at higher rpms and intermittent knock sensors tripping. He even added an additional 20hp compared to pro chargers emailed tune. He will be getting more of my money and car for sure. read more

The worst customer service came off very cocky, asked a question about something on my vehicle and he kept talking about something totally different then what I was asking and gave no help at all and didn't seem very knowledgeable from the advice he was giving. Would not recommend this shop to anyone read more

I had a great experience with Newtech Performance. Nick was very knowledgeable and turned my 2017 Chevy SS into a Monster. read more

I took my lsa swapped silverado that drove their and got tuned by Nick and had to get towed back home took it back twice to get it fixed never did he accomplish to get it running right do not I repeat do not take a car here that he did not build truck ran better before his "tune" read more

Lol, damn I read all these reviews even before I went there. Bunch of salty females . Well after like 20 MFers said this was the spot, they were right. Got an appointment pretty close to a week after I asked, and within 5 minutes of him asking questions, I left, got called back 2 hours later and it was done. Not only did he finish but let me know what I had to do to squeeze out of my LS and that I could come back if I made some changes. All the hate on here y'all act like you were going to see a psychiatrist, it's a shop, where they work on cars. Funniest part about all the custies being all mad is there probably is a funny other side of the story too ‍. I'd recommend a tune from this shop to anyone. So far so good with NewTech. read more

I have a LS swap with cam upgrade in dire need of a tune and Rick was very professional and most of all knowledgeable enough to get me running and gave me input on what I can do next for optimum performance, I would definitely recommend him read more

Brought my 69 Camaro to Nick after a LS Swap from VK Autosport in Redwood City. The swap shop completely hacked my car...gave it to me smoking out of the exhaust, bad sensors installed, no cam retaining plate installed, left tools in the air cleaner etc. etc....anyway, brought it to Nick for a diagnosis. He was able to plug in his computer, diagnose the issues, switched out bad sensors, installed a retaining plate and got my car safe to drive. I was appalled when I initially heard the new of the bad swap, but Nick gave light at the end of the tunnel. Josh next door chimed in and was helpful too. Once the break in is done, I will definitely bring the car back to Nick for a full tune and dyno. This guy is worth every penny just from his knowledge alone. read more

Just got my car tuned by Nick and he did an awesome job, I'm very happy with the numbers my car made and it drives way better. I'd recommend! read more

Great shop and amazing work. If you need a work / tune go to Josh and Nick. I am very pleased with my car

Nick laid a base tune had my car running super rich heard a bunch of story's about this guy since then about how he's messed up a lot of other cars charged me 500 for nothing went and got a tune from someone else paid 350 with Dyno tune I think he just doesn't care if he didn't build your car not sure but I wouldn't recommend ANYONE to bring your car to him. read more

Nick is the man when it comes to tuning LS engines. I brought my 02 Camaro in for a leak in my Valley cover and a retune for a MagnaFlow Cat-Back. The car is running awesome and I am ready to enjoy the weekends this summer thanks to Nick newtech performance. read more

Newtech Performance - Thanks to Nick from new tech for the awesome work on the LS1 engine - Auto Repair Near Me - Hayward, California

Nick is a magician - his tuning skills are tremendous, particularly with LS motors. Car runs smoothly, is very responsive, idles better, the transmission is much happier. Excellent all around - you can't beat $600 for an HP tune on a dyno! read more

I give new tech performance 5 stars Nick the owner of the company knows his shit he's not much of a talker more of the businessman but with a lot of Technology stuffed in that head of his if you got a Corvette or you got a Camaro he does great dyno tuning he knows what you need and he knows where to get it so thank you Nick I know we'll be working or you will be working on my car again thanks read more

Great guy! Tuned my C7 with long tube headers, very knowledgeable and trustworthy I am definitely going back I recommend for sure if you have a LS. read more

Did a dyno tune in rpm automotive made 312 horse and 290 Pounds of torque came to new tech made 331 horse power and 325 pounds of torque definitely recommend this shop for those truck owners with a cam read more

I have brought my Camaro here and have had very good performance installs. Good understanding of my needs and car is usually ready as estimated. My only issue is that getting a hold of someone on the phone is difficult. Would visit again. read more

Had my V tuned by Nick twice. 1st time my car picked up close to 70whp from pulley alone. Had some issues after, not from the tune, but the effects of a collapsed brick. He took a look at the tune again and told my I was having really high IAT2. I later addressed the issue and added e85. He got about another 90whp gain from that tune. Nick has been great with my car and I would definitely recommend his tuning services. Can't speak on install as I haven't had him wrench on my car, but wouldn't have a problem having him work on my car if needed. read more

I never made any demands of any prices. It's funny how shady people make up some odd stories. I never mentioned ANYTHING about Yelp. He did a 600$ dynotune job, promised that if I come back n he'll fine tune it. He refused and asked for more than what he said I could get it fine tuned for. Worst part is the fuel pressure was off. Such a hack. read more

Best LS based tuner in the Bay area. Nick knows what he's doing and will let you know what you need to do if your not hitting your expected numbers, usually because you've mismatched your build somewhere. Bring something built right and he'll squeeze all he can out of it. He'll put in the time and do what he can otherwise, but don't be mad if your numbers are lower than expected. read more

NICK IS A JOKE! OK tuner, HORRIBLE business owner. If your exhaust fumes even touch the dyno, expect to pay $200. If you have an appointment, be prepared to wait literally 3 hours. If Nick screws up, be prepared to drive all the way back and be re-charged again. Josh is a legit mechanic though read more

If you need performance work done, this is the place to go! In house dyno tuning, installs, parts, etc. Nick has done a lot of work on my car's in the past, and id never hesitate to bring another car back to him! Josh and Jesus arent too bad either, haha. Great set of guys, and a great shop! read more

newtech is horrible. I tried to have a clutch installed. they told me it would take a few hours. after several days and destroying the brand new clutch I brought in I got my car back. I then took it to another shop who installed the clutch in about 4 hours. they installed a brand new moser rear end. everything seemed ok. after blowing out two axle seals and pinon seal I called moser. Moser said it either was over filled, or not properly vented. I wish I had taken pictures of they plastic tube they stuck in the rear end to vent it. This is a joke. Another friend of mine with a saleen went thru six months of problems with these guys and a supercharger install. I like Josh, but they have alot of problems. Ive always heard bad things about Nick. Do not take your car to this place unless you want problems and headaches. read more

Nick (owner) doesnt talk much, but does great tuning. I have plenty of friends that go to him and never had any problems. His worker Josh is a cool guy and does great work. work done: installed parts and tuned my camaro ls1 read more

I use Newtech for Dyno runs ... Great shop, guys are extremely friendly and always willing to do that extra pull when you need it !

I don't know how you guys can rate Newtech so high. Nick provided horrible customer service, didn't even attempt to make eye contact when I asked him a question, and wasn't very friendly at all. He tunes the cars way too rich, and you get a terrible gas smell that is unbearable. He only did like two pulls when he tuned my car, tunes for wide open throttle only, and didn't try hard enough to squeeze more power out of the car. If you want a real tune, I'd recommend TPS in Campbell. read more

Nick does good work. He did headers and a tune on my 2002 z06 and I am very happy. The car has a little more power from the headers and the tune really smoothed out the power. The price was right and the work was good. I think the bad reviews come from personality conflict, not workmanship. read more

I have been going to Nick for about 7 years now. Most people that I know go to him as well. He is the most knowledgeable tuner I have known . The suggestions and advice he gives are legit and really do make a difference . He is not like other shops that suggest to purchase their "custom" set up(s) in order to make some power. Nick thoroughly went through all the parameters on my car for both power and better streetability . He definitely knows what he is doing. I will conclude with an observation I've made: my car outperforms cars that were tuned by other shops claiming to have the same or + 40-55 HP . read more

Nick, Jesus, and Josh are cool people and will take care of you. Anything i need done i take it to them.

Nick did an excellent job tuning my Trans am. I have never had a single problem with any of his tunes dating as far back to about 2005. This go around he took the extra time on the dyno to clean up the tune and it drives beautifully. Made some good recommendations as far as where I can improve upon as far as the engine goes. The last tune with Nick the car drove without a problem for 6 years to the current setup. Highly recommend as he will take care of you! read more

I brought my corvette to Nick for a dyno tune and he did a great job. When I arrived I saw a few other corvettes which made me think I was at the right place. He knows what hes talking about and I would definitely recommend him for any tuning. I'll be returning next time I need a tune. read more

Be careful with these guys. after picking up my car and started to get on the road i instantly started having problems. here's my list, fuel leaks, poor tune, blowing out cats, multiple scratches on bumper, bumper corners was broke on the inside so when it was put back on it didnt line up and the ends where popping off, hood alignment was changed and barley popped open, boostapump amp was not in the the right spot which could potentially cause electrical fire, fuel lines put on backwards (cross over was on the back not front) and damaged, rear end looks like it has been tampered with and resealed with a weird sealant which was poorly put on (looks like a seal blew probably on the dyno and then got band aid over to cover up), and gum was stepped on and now is stuck on my driver side floor mat. i took my car back numerous times for lousy tune which where basic things that should have been taken into consideration when tuning a forced induction set up and fuel leak. fuel leak was never fixed and ended up fixing it myself. had to take my car into a auto body shop to get bumper fixed. then i started to blow out cats ( good tune should not be blowing cats).so i took my car to their competitor in Fremont and got a re-tune and numerous things fixed that newtech created for me. please take this review into consideration because this shop created the biggest nightmare Ive ever had. DO NOT TAKE YOUR CAR TO NEWTECH PERFORMANCE!!! read more

this guy charged me 550 bucks to safe tune my truck. told me to drive it and break it in before he would dyno it. said come back and it would be another 150 to dyno and i would be done. after numerous calls have gone unanswered and he never opens his shop. he is a scammer and a liar. do not take your vehicle here. take it to synergy in fremont and get it done right the first time. read more
