Real Reviews. Real Results.
Blake was able to get my truck in on incredibly short notice and managed to get everything I needed done in about a day, I would've spent a fortune at any other shop, but not here, he was honest, and straight forward, told me everything in detail and skipped all the nonsense. I will be returning here again, exemplary

Blake did an excellent job disabling the AFM/DOD on my Chevy 5.3. He was thorough, knowledgeable, and clearly knew exactly what he was doing. While working on the truck, he also caught that one of my sway bar end links was broken and took care of that as well, which I really appreciated. He’s dependable, honest, and doesn’t BS you — just straightforward, quality work. Highly recommend if you want the job done right.

Had my truck tuned here and couldn’t be happier with the experience. Super professional, very diligent with his work, and had everything done quicker than I expected. You can tell he really knows his stuff and takes pride in doing the job right. He also knows a ton about Gen 5 trucks (2014-2019), and his tuning is way more in-depth than what most other places are doing. It’s clear he takes the time to really dial everything in instead of just throwing a basic tune on it
