Kenny has been building my cars since the mid 90's and my GT R is the fourth car he has built for me. Each one has been spectacular and reliable. The GT R just dynoed at over 1000 hp and over 860 ft lbs of torque! I can't say enough good things about Kenny, Tony, Kevin and all the guys in the shop. Don't settle for less when in Jo Tech you have the best!

  These guys are SICK!!! The quality is unsurpassed. If you're even thinking of improving your ride, you've GOTTA check these guys out!!!

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

  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.

  Great customer service, highly recommended this place.

  Ditto all the positive remarks. These guys can squeeze hp out of a gas cap. A-1 service and really cool people. No complaints.

  I first started coming to this shop every now and then because a few of my friends have gotten their cars worked on here. Knowing me before I take my car anywhere, I do a lot of research on shops before I take my car to and ask for feedback from customers and friends. When it was time to get my dyno tune and other stuff done to my car, Jotech wasn’t on my list. Anyway, so I decided to contact Kevin to see what he can do or what he offers. Went up there and talked to him and Seth. They seemed to know what they’re talking about Fast forward: Now the car runs better than the last shop who tuned my car. I’m really happy they did what they could to improve the HP as well as driveability and efficiency. Cant explain in detail what they exactly did but these guys know their sh*t!!! Staff is also friendly and will take time out of their day to make sure you’re taken care of!

  I have known Kenny and the guys since the late 90's. They have always been welcoming even if you were just figuring up a dream list for your ride. Even to this day, the guys always take the time to say hey and chat about anything even if it's not related to a sale. I recommend these guys highly to anyone who wants to seperate themselves from the norm on the street or the track.

  Great product, great staff, the best place to go. Thanks Kenny.

  This place is awesome Great shop,great owner,great place for GTR upgrades but they also work on just about anything,reasonable prices on there work hooked my G37 up nice.
