J & J Speed Shop

Master at his craft! He knows what he is doing... not even the same vehicle. He changed the shift points of the transmission and it feels like a different transmission. I was very impressed at how smooth everything went. Great price. I will recommend him and bring my vehicles here. Thanks Jason.

Jason was super helpful with identifying the issues with my Escalade and, aside from doing the needed repairs, he also gave it a performance engine and transmission tune. Runs and drives way better than before. Very knowledgeable and reasonable prices. Thanks Jason!

I've had nothing but positive experiences with J&J. I originally went in to ask a few questions about a procharger kit. After speaking with Jason, it was clear he knew what he was talking about and just a wealth of knowledge. I've been to the shop multiple time and have also had a good experience. I ended up purchasing the kit from J&J and he has been very helpful throughout the entire process. Its refreshing to deal with someone who is honest and does what he says. Definitely will continue to deal with Jason.

Five stars, this guy knows his stuff. Brought my C5 corvette in for a tune and he dialed it in perfectly. His work speaks for itself and will be back again for other performance mods. Highly recommend

I had the classic intake manifold runner issue on my 2017 mustang and I was eager to get it back on the road for the upcoming summer. I ordered an aftermarket VMP manifold and installed it with a few modifications, but knew I would need a tune. Well, I wrapped up the install a Thursday night with the car running poorly (as expected) and reached to Jason on Friday. This guy got me in on the same day I called and knew exactly what my car needed for a tune! Awesome job and I am very satisfied with his communication and quick response time. Felt like I knew him for years after only talking for a few minutes. Will be going to him again in the near future for other needs
