The truck runs great tho, I'm super happy bro.
It pulls good man and runs great — definitely runs better too. Very happy.
The truck runs great down the road man, I can't thank you enough.
Ye buddy you nailed it. It runs better than it ever has since the cam install — and the idle is so dialed now!
Got it, sounds good man. I got the tune flashed, it's starting a lot easier now. I'm gonna drive it and make sure it's all good — I can tell a difference already driving it.
Bro 20 stars — did a Chopacabra cam swap on 37s and 4.56 rear gears, they did everything. Super responsive, fixed every issue I had. 10 out of 10, will tune again. If you need something as close to perfect as possible, this is the place.
Great guy! Good example of an honest mechanic and tuner that knows his job. Highly recommend — will be using him again.
Normally I wouldn't leave a review, but I'm so pleased with this place I had to share. I recently had to replace the cam and lifters in my 2011 Ram 1500 — went with the Chopacabra from Texas Speed and Mopar lifters. After the cam swap I needed help tuning. I was fortunate enough to come across Jason's YouTube which led me to his website. Quickly sent him an email with my factory tune file and purchased his pre-written tune file. This guy is awesome! He started communicating right away, informed me when my file was ready. Great prices and excellent work.
