Did a great job installing short shifter on my corvette ..............................://:$47;$;;$$;8&4!;$;!4&4

Got coolant leak repair done on my BMW m240i. They were super quick and super straightforward.

Competitive pricing and quick services. Definitely will hit up again for future projects

Took my 2026 M4 to Speed Logic for help with tuning and getting everything dialed in on MHD. I'm running a flex fuel setup (E40 mix) and they really knew what they were doing with the S58 platform. They helped make sure everything was set up correctly and the car runs way smoother and stronger now. You can tell they have a lot of experience with these cars, especially when it comes to tuning and performance setups. Communication was Great and they didn't just rush me out, they actually explained things which I appreciated. Overall really good experience and im definitely go back for future mods. read more

Way to expensive for independent bmw repair shop... And I never heard back from them for a transmission replacement estimate.

So after 4 visits with Speed logic over 4years of my experience with them, i think i should probably leave a review as this place can be the best choice for those BMW tuners in LA/OC. I first started to go to speed logic with my E90 for its maintenance works. Their quality of work and the way they treat customers by everyone and obviously Rob is great. You can tell that they dont just under treat anyone. I honestly think the owner appreciates every businesses coming on his way and he always tries to meet customers' expectations and its always met or above. Today i have taken my bmw i3 for lowering spring installation and everything went perfect from making an appt with them to getting my car back. Their price is VERY competitive for the quality of work they do. Everyone is professional. Thorough with explanation. If something goes wrong, they consider. Frankly speaking i reached out to many shops for this works and i still chose speed logic although i live 40+ miles and i am super satisfied that i did with quality of work they do each time read more

Came in for a simple headlight swap. They made a false diagnosis, ordered me a different part, just for the problem with my headlight to still exist. Hours of time wasted. Extremely difficult (2+ weeks) to get anyone on the phone at speedlogic so we could try and solve the issue. Lastly, the reports they give their clients are exaggerated to get you to schedule more service work. Claimed I needed MAJOR services done. 2 other shops denied the work even needed to be performed. Staff is kind and front desk manager tries to be accommodating. Will not be returning. read more

I've been taking my BMW M2 here for almost a year to all the service and maintenance done. So far some of the work and service includes: - Oil and filter change - Coolant change - Brake fluid change - Spark plug set change - Metal charge pipe install - CSF intercooler install - Downpipe Install - Lower front splitter install - Bootmod3 license - Soon, will be replacing my front brake pads with EBC yellow stuff As you can see, Speed Logic has performed an extensive amount of service, maintenance, as well as upgrades on my vehicle. I'm very satisfied with the quality of the work, I trust them to work on my vehicle any day, I would highly recommend them for any service on your BMW. In addition, Ian is always very helpful, responsive to my inquiries. It's also very convenient to be able to communicate with them via text. They also provide a complete vehicle inspection link after each service. read more

This is the only place I trust with my car. They are super honest, and do great work. Anything from small maintenance to upgrading turbos, they got you. They have been taking care of my 335i and I for 9 years now, since their old Fullerton location, and car is still going strong. read more

EXCELLENT service Had them install a CSF heat exchanger and do a brake fluid flush on my M2 Competition. Great communication, fast turnaround, and everything was straight forward. No other shop around can beat what you pay for. read more

Speed Logic Automotive - These guys took care of me after dealing with an issue that another shop caused. Top notch quality work done by SpeedLogic. - Auto Customization Near Me - Westminster, California

Few months ago, I was having AC issues that had two places couldnt figure out. One of those places being Crevier BMW. All Crevier BMW cared about was the dollar amount, assuming the issue was going to be the condensor which wouldve been at least 5k. I took it in to speed logic to figure out where the leak was. They kept my car for about 4 days filled up my freon and ran a few tests. No leak was detected and my cars AC has been working completely fine. Rob cares about his craft and takes his time to get the root cause. You can trust this place to get quality service. Thank you read more

These guys perform top quality work in a fast time frame. So far, they have installed a Burger MotorSports JB4 ecu tune, BMS charge pipe with BOV, CG Precision downpipe, changed my oil/brake pads, Bonoss wheel spacers, lowered on Eibach springs with special requests followed. This is the shop to go to! read more

All I can say is that this place is hands down the best BMW shop around. After getting the runaround from a few other shops to install new engine mounts on my car I happened to come across Speed Logic through a Yelp search. I gave them a call on a Monday and I was in the shop on Wednesday morning. Only took them 2 hours to complete a job that everyone else said would take all day. Their customer service was top notch and they kept me updated on everything Along the way. I will definitely be back and recommend them to everyone I know! read more

If you want honest and reliable service, without a doubt, bring your vehicle!! I know I will NEVER be sold something I didn't need!! My husband wanted to do some upgrades to his BMW 335is and he received nothing but honest opinions on what was recommended, wasn't the most expensive, asked all the appropriate questions and ended up with the perfect setup. Thank you! read more

Speed Logic Automotive is the prime example of a performance shop that gives you that one stop shop feeling. I have never felt more at ease knowing that I am taking my vehicle to a shop that knows what they're doing based off of years of experience within the BMW community. I had a ton of other recommendations to go to other shops but Speed Logic was recommended over and over by locals and friends. I live over 2 hours way and will continue to take my f80 m3 here for any performance needs or regular maintenance (turbo installs, port injection , oil change, some plugs , etc...) Rob, Ian, Tim, Sidney and the rest of the crew is what makes Speed Logic and I can't thank you guys enough for taking care of me and my car even making accommodations for dropping off parts closer to my house instead of traveling all the way back to the shop making it easier for me (they will go above and beyond even if they aren't entitled to) Prices are very reasonable, you pay for their years of experience. Trust me and take your car here for all your go fast needs or regular maintenance they do it all. I never make reviews this long but y'all deserve it thank you again read more

N54 Owner here, From Ian at the front to Rob at the back this team is fantastic. They did all my service maintenance, bolt ons, and tune. Even had them take care of my sons e92 328i after they did such nice work with mine. I highly recommend them for any BMW work especially E9x platforms. Will be returning for any and all service needs! read more

I drove 2 hours down from Palmdale for a simple stage 1 tune. I was very impatient and decided to take the drive around 3 in the afternoon Arrived at 5 (closing time) Left around 5:45 with a tune and VALUABLE knowledge They accommodated me and stayed late to flash my car, they were very professional and friendly you can tell they love what they do, They all drive modded bmws Daud took care of me and answered all my 100+ questions, (don't let his age fool you! The guy is a genuine bimmer wizard) Broke down what a tune is, showed me all my different types of options and explained the positives and negatives in each. Then proceeded to explain the bootmod3 platform for me, (as it is my first time using it) and took his time in doing so. Even tho the guy had to go home and I already paid him, before I left he walked me thru the entire application, and had one of his techs inspect my car (no extra charge) as well as bring to my attention an oil leak that I was not aware I had. Will be coming back here for any and everything I need. WORTH THE DRIVE AND EVERY PENNY. I would rather come to these guys rather then any Indy shop where I live. The amount of professionalism and kindness I received made the drive back home so redeeming. read more

If I could give them no stars I would I payed 1,800 dollars to have them replace my oil filter housing along with a rear main seal 6 to 7 months ago we'll my oil filter housing began leaking again mind you I hardly drive this vehicle I've only added 4,000 additional miles since they previously worked on the vehicle know as I was driving due to the leak on the oil filter housing the serpentine belt ended up sliding out and causing an even bigger issue I've been in contact with this place EAN and basically they are not trying to take responsibly I have not received a phone call not even a quote it's. Been over a week horrible customer service no accountability I would suggest everyone stays away they are stealing people's hard armed money just disgusting. N54 BMWs stay away they almost ruined my engine... read more

Charge pipe blew out yesterday so I woke up this morning, called about 6 different shops and no one could take me in for a week. Called Speed Logic, was told they were booked but to drop the car off anyways and they would try to squeeze me in and finish it by tomorrow afternoon. Dropped off the car at 11am and at 3pm I got a call from Daud that the car was ready. Amazing customer service and I can't thank them enough for such a quick turn around. 5 stars! Thank you Daud and Rob. read more

Great honest people. My son has a 2018 BMW 540i engine is B58, and he wanted to do bootmod3 with downpipe to get all the sound of bangs and pops so I have found speed logic on yelp, and they are very responsive to all the questions. My son took the car in for stage 2, and they replaced the spark plugs, install downpipe and bootmod3. The car was amazing with all the sounds that he wanted, and 2 weeks later I made a huge mistake by taking the car to BMW dealership to repair the front grill, and they updated all the computer system so after that no more sounds. I have contacted speed logic, and there is no way to do the bootmod3 in any updated BMW software for 2020 and 2021. If you have any tune in your car don't it to a dealer for any service. I decided to remove the downpipe, and install the original cat back on the car. Ian helped me all the way with answering all my questions, and also helped with replacing the downpipe with the original cat. If you need any work to be done on your BMW then I totally recommend you to contact these guys as they are the best in the business. Thank you Ian, and Rob for all your help. read more

While I wasn't able to use their service they responding promptly and politely explained they weren't the correct shop for the work I'm looking for. I feel like more places should get a positive review for great customer service no matter if it worked out or not! read more

I'm extremely glad I found Speed Logic Automotive and will absolutely be trusting them as my primary auto shop for my BMW F30. Rob is the most detail oriented and honest shop owner I've ever come across. He's extremely courteous, professional, and communicative. They did an amazing job upgrading my suspension and brakes until everything was tuned perfectly. Rob patiently broke down every level of detail possible to ensure I fully understood advantages and disadvantages of my decisions, and the work was executed perfectly and carefully. Speed Logic portrays a clear level of passion for their craft and treat what they do as an art. This, combined with their honesty and trustworthiness is ultimately the key to being successful in this business, and Speed Logic is well on their way to the top. read more

I been to this place first time and One of my friend recommended this place for too see my car has an issue ( drivetrain malfunction message displayed on the dashboard). I met the guy name "Rob" he is a senior technician over 8+ years of experience in this industry, he is so knowledgeable and good hands with the engines and all the stuff he found the issue was with tuner (JB stage 1) I've installed and it was damaged with water contact and causing the drivetrains malfunction error code and he resolved it and he did the full scanning of my car and recommended few things like (oil change,spark plugs and coils and walnut blasting break fluid ) flesh ) I did it. Once all maintenances are done he took a time to explain each and everything so much detailed.. and what was reason for his recommendations about oillchange and all .Rob is the right guy for bmw ( especially N54,55 engines ) read more

I recently discovered Speed Logic after receiving a few recommendations online. I brought in my BMW 335i n54. The 5 stars are true and the whole crew here are really experts and professional at what they do. My story is unique and I had learned a lot working with them along the way. Here's my advise for any new customers; 1) if you plan on purchasing any aftermarket parts for mods, make sure you have all complete parts to not delay the build. In my case, I purchased an oil cooler kit with missing parts and it took time for extra parts to be ordered and shipped. To save time, I'd recommend that you just let Speed Logic do all the ordering for you in advance on your behalf to ensure all the parts are complete the first time around. 2) Please be patient. These guys are super busy and they always have a full lineup of cars out the door. I stopped by the shop and seen it first hand. They work fast and smart, but please respect their time. The wait is worth it! The crew here takes a different approach on customer service. Rob really took the time to get to know me and broke down every little detail what he worked on and recommended maintenance. Thanks again read more

Truly grade A service and nothing done here is Mickey Mouse. I like their approach of doing things right and providing real solutions to problems rather than alternatives. My headaches were relieved and much money saved with a piece of mind that services are done proper. To have their level of expertise at prices quoted 30-40% below dealership is truly hard to find. I got quotes from multiple shops before settling and had all my repairs done by SpeedLogic. From personal experience, DIYs Instructions and How To's videos can only take you so far until you realized you fucked something else up during the process. However, your problems are always welcomed w open arms here. Tips: book an appointment before coming in, do not push answers before your car is even looked at, combo repairs will save you money, respect their time and be patient read more

Took my BMW in and they updated my software and locked my DME. Lesson learned the hard way. Needed bench unlock to re-flash Bootmod3. Shopped around and requested quote on Sunday 8/7. Even though they were closed Rob responded quick. Ian called Monday 8/8 to go over more details and scheduled appointment for 8/9. They performed bench unlock in about an hour. Had an issue flashing Bootmod3 and Rob let me know to reach out to them as this sometimes happens. Bootmod3 did their magic on their end and I'm now able to flash my car again! Thanks to Rob and Ian for being quick and resourceful! read more
