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.

Been dealing with Blake over the years buying engines-- It was nice enough to try out his work on my wife's 69 Chevelle- and it is amazing-the sound-the power etc. Also while he was working on it found a few other problems he addressed. He also worked on another car of ours and was very happy with that work also. Good luck Blake you have our support.
