We can and do tune a LOT of stock trucks and cars to optimize performance and drivability! This Tahoe was a prime example! More power, better shifting, addressing DOD/AFM and torque converter issues, changing speed limiters, and addressing auto start stop are just a few reasons to have us tune your stock(ish) car or truck!

We are still looking for a qualified technician. Somebody out there wants to make slow stuff fast! We are NOT looking to have to train from the ground up on this position, we need someone that can come in with basic skills and get work moving. Pay is a percentage of labor rate based on skill. To apply, message the shop or call (573) 718-8733

We were able to pick up big gains with tuning on this 06 Escalade. This truck was bought with a 5.3L and cam with unknown tune. We cleaned it up and had HUGE gains across the power curve to get this truck running way better!
