Really helpful and knowledgeable. Looking forward to using them again in the future

  I live In northern Virginia and still have the best customer service they tune my GTR and answer all my emails promptly thank you

  Took my 6MT G35 sedan to Jotech for a tune. Friendly staff, they were ready for me as scheduled. In and out in a couple hours with an extra 16 hp and 22 lb-ft torque. Car feels more responsive, noticeably more power through the entire rpm range. Very happy with the work they did.

  My expectations were exceeded! I had first visited Jotech last year shortly after picking up my 14 BE. I had read online about some of the packages that they offered, and I wanted to get a little bit more info from them. Tony, Kevin, and Kenny were extremely helpful and welcoming to me. They educated me better about my car and its capabilities for improved performance, as well as the preventative maintenance that they offer for the car (cheaper than the dealer btw). This past week I had them install a stage 2 on my car, and I am blown away, again! The quality of their work, and their knowledge and expertise is top shelf, and they were 100% correct that the upgrades completely transform the car into a different monster! While I am very happy and content with the car right now, I can see me taking my car back to them for further upgrades in the future! If you are looking for a top notch shop to improve the performance of your car, look no further! Thanks again!

  Had a stage 2 gtr and I have never experienced fun reliability or controllability like that in a car definitely recommend this place. Kenny Tran will dumb everything he does down to where a baby could understand and it's a great place to go and have fun and talk about cars!

  I took my 05 S2000 with Kraftwerks SC in last Saturday for a dyno tune. Kevin and Seth were very friendly, polite and professional to my wife and I. Seth did a great tuning on the car. I had too low of octane, so he drained the fuel while I went for a better fuel. He gained me an additional 40hp! Final number was 425 on 93 octane. On leaving the dyno we discovered the VTEC bolts had shook loose and I had lost a quart of oil. Not having any with me he tightened the bolts and fronted me a quart of oil. That IS customer service. I'm sorry that Tony and Kenny were MIA and I didn't get to meet ya'll, Perhaps next time I make the 5 hour ride over. Well worth the long drive. A Great service at a very reasonable price. Many Many Thanks Guys!!!

  Best shop I've ever been to. These guys are amazing and will take care of you. Great tuner, great prices, great work. The only place I'll ever take my GT-R. Kenny himself has helped me out and has been a great resource.

  I've been friends with Kenny since the late 90's so naturally I wouldn't give anyone else my money. Huge clean showroom with lots of goodies to look at and touch. I do most work myself but when it comes to tuning, Kenny is my go to guy. He tuned my S2009 and 370Z.

  I remember the first time I walked in there, amazing experience. Kenny is the best. I would recommend these guys to anyone who wants a GTR that's around 600-1000hp as a safe daily driver.

  This place works on amazing cars. I have had a rough start with my infiniti and the manager and owner have helped me a lot to get it to the perfect condition. I'm very happy I was directed to them. I won't let anyone else put a wrench to my car.
