DT Performance

Brought my 2017 GLI to them to be tuned. She’s an old girl at almost 170k at the time I brought her to them. I really appreciated the teams expertise and honesty in that they told me due to such high mileage on the original engine, they weren’t comfortable doing an ECU tune since there’d be a good chance I blow my engine if they did. It is my daily so I wasn’t looking for a ton of performance anyway- just something to fix the CEL due to the catless downpipe, some pops and bangs, and minor TCU adjustments to make the driving experience better since I drive so much. That’s exactly what they gave me and I couldn’t be happier with the outcome. They even dropped the price a decent amount from what they originally quoted me since they weren’t doing the ECU tune. Ended up leaving with stage 2 TCU

I would highly recommend working with this tuner with any German car brought over my Volkswagen and he had great general knowledge regarding it. He gave me good suggestions that would best suit the car and the engine health. Worked with Serg and he gave a great quote and the quality of the work is perfect. Would come again with any other German car I have!

I highly recommend Serge and his Team at DT Performance. They are reliable, honest, and affordable. I have been using their services for 5+ years and for a few of my Audi’s. They have preformed an engine rebuild, a transmission tune, multiple oil changes and more. Highly recommend!

I was recommended by the Audi community to check out Sergi and his shop, and I'm glad I did. I have an RSQ8 and previously had a piggyback module installed in my car. After speaking with Sergi numerous times online and on the phone, he said, "I can prove to you that the module is not as good as advertised." As someone who works in tech, I appreciated that Sergi was so kind as to explain how everything works. I scheduled an appointment to test out his ECU Stage 1 and TCU Stage 2 tune. The data showed why the module was not great, which again, I greatly appreciate. Post-tune, oh my god, the car is a different beast! And the data also doesn't lie. You know when someone just knows how to press X amount of buttons to enter a specific mode on a car for tuning? That's what I want from a person wh

DT Performance is where you take your German vehicle with trust that it will be corrected. Sergei is the owner and his team of professionals do everything. Air suspension. Wheel bearings. Electronic issues. The prices are a fraction of what the dealer charges. If I ever sell my car, the repairs will show up on the car fax. This is a highly trustworthy and reliable service shop. I can only say that about one other place. That’s AKAR in Middletown. But I wouldn’t take a German car anywhere other than DT.
