I would look into the other similar 1 star review on here about poor communication and process before booking a tune here, and who knows probably saved myself a headache avoiding getting my vehicles tuned here. I had 4 exotics that I planned to get a tune here, the first one being a vehicle that was delayed on some parts that were not in my control. Each delivery confirmation I received from the supplier had a delay and unfortunately it was 3x. The technician I spoke with on the phone told me that rescheduling is okay and that he would take care of it and understands things happen that are not in his control. Super nice dude btw, but it seems like there's a manager and owner above him that didn't agree with this and was pretty upset. Also totally okay, but the communication and what I was told initially did not match. I expressed my feedback and the manager didn't seem to really listen much and then the owner grabbed the phone and said to go somewhere else and waste someone else's time. Um alright...? Well the call was on speaker at the performance shop I was at and I guess I'm glad it was nice to have some witnesses for that comedy skit. I'm sure the owner will reply here and say they tried to reschedule 3-4x and about not making money, but the thing is the person I was in contact with told me otherwise and it was not a problem rescheduling if delays happened, and tried to squeeze me in sooner than later every time. Also P.S to the owner, you can keep the $150 deposit. You guys seemed like you were very upset about "not making any money!!!"

These guys custom tuned my Mercedes C63 AMG on dyno! Car feels crazy now! It feels much much more responsive and powerful. I definitely recommend OGPT for tuning!

I recently had a stage 2 tuning and performance upgrade done on my car at OG Performance and Tuning, and I couldn't be happier with the results. The team at ERCAN was knowledgeable, professional, and provided excellent customer service throughout the entire process. The increase in horsepower was noticeable immediately and has made a significant difference in the performance of my car. I highly recommend OG Performance and Tuning to anyone looking for quality automotive services. Five stars!

I was here for upgrading my car modules to the new version. I then realized they offer performance tuning and retrofit programming/coding. There is a lot of cool things going on here. I will definitely be back for using their performance tuning services.

Have been running with their custom stage2 engine and transmission tune for 3 years now on my bmw 440i. Literally had 0 issue on my car. All service and maintenance done by them. I couldn’t be happier with the results and reliability of my car. Thank you Ercan!

Very professional and would recommend this place to anyone who is looking to get the most out of your vehicle. I Felt my car had not been performing to its full capability in years until i left this place. Now it’s performing better than it ever has before! Highly recommended and if you wanna be cheap, this isn’t the place. It’s all about quality if you truly care. Keep that in mind!

I highly recommend getting work done to your car here they are very knowledgeable and take their time to perfect the work. I came in for a tune and it completely changed how the car performs. I will definitely be recommending this place to anyone who wants to tune their car or work done on it.

i just happened to find these guys through Instagram and happen to see all the vehicles that they tuned among a customer that they helped out of mine. That really shed some light on a particular issue We were having had it not been for them And the great service they offered, I wouldn't be able to help my customer for one. So I thought I'd give them a try for my personal vehicle. Due to seeing amount of european vehicles, they have performed a great amount of service on. As a person who had multiple vehicles tuned before, I have an understanding of how things work. From the appointment time to the drop off to the pickup, what's all flawless. Drove my vehicle home I had no issues. Since then, and many months later, still running great, thank you so much to Ercan and his team,And I plan to do much more business with them.

I could not be happier with the service I received at OG Performance! Ercan and his team brought my BMW 340i back to life after the car refused to start. Then they took the time to help me program a custom stage 2 tune. The end result is amazing. The car is significantly more powerful and responsive, and it sounds great. I definitely recommend OG Performance to anyone that needs professional tuning services to fix or enhance their car’s overall performance. Thank you Ercan!

had a very disappointing experience with OG Performance & Tuning in Santa Clara and feel it’s important to share this for anyone considering bringing their car here. The main issue is that I showed up to a confirmed dyno tuning appointment and the service never happened, yet the shop refused to return my $100 deposit. I scheduled a dyno tuning appointment for February 27, 2026 at 11:00 AM and arrived on time as agreed. The appointment had been confirmed beforehand. There ended up being a misunderstanding about bringing E85 fuel with me. I understand that miscommunications can happen, but the way the situation was handled was extremely unprofessional. Instead of trying to work through the issue or reschedule in a reasonable way, I was told I would need to pay an additional $500. Because of this, the tuning did not end up happening. Before the appointment I had already sent a $100 deposit. Since the service was never performed, I asked if the deposit could be refunded. I was told the deposit would not be returned and the only option offered was store credit. I explained that I wasn’t interested in store credit since the service never happened, but they still refused to return the deposit. It also felt like they simply didn’t want to work with me or my mechanic and were more interested in keeping the deposit rather than trying to resolve the situation. I even asked if they had any spare gas canisters I could borrow so I could quickly grab E85 nearby and continue with the appointment, but that was refused as well. Another important point is that when I sent the deposit, it was never stated anywhere that the deposit was non-refundable. Finding out afterward that it would be kept even though the service wasn’t performed was very frustrating. As a customer, I expected a much higher level of professionalism and customer service, especially for a scheduled tuning appointment. I understand that shops have policies and schedules to manage, but keeping a customer’s deposit when the service wasn’t performed and handling the situation this way left a very bad impression. Based on my experience, I would strongly recommend that anyone considering this shop confirm every detail ahead of time and clearly understand how their deposits are handled before booking.

I recently ordered an aftermarket exhaust for my BMW through OGPT and they also provided installation as well. The folks at OGPT were very friendly and helpful and made sure that I received the best experience for the modification. They provided proper customer service and communicated updates appropriately. Highly recommend them for any modifications!

I searched extensively for a tuning shop that could perform both a Stage 1 tune and a transmission tune for my 2016 BMW 535d. In my area, no local shops were able to take on the job. After spending a considerable amount of time making calls and researching online, I finally found OG in Santa Clara. From the first phone call, they were knowledgeable and confident they could deliver exactly what I was looking for. When I arrived, I was greeted promptly and professionally. The work was completed on time and to a very high standard. After the tune, they put my car on the dyno, and I was genuinely impressed by the noticeable increase in power and efficiency. Now, after driving it for a couple of months, I can confidently say the improvements are substantial—not just in performance, but also in fuel economy. I highly recommend OG to anyone considering a Stage 1 tune. The results made my BMW feel like a brand-new car again.
