Went there today to see if they had a fitting for my water/meth kit. They couldn't get a hold of snow performance so they literally took the fitting out of a box to a new kit. They could have made me wait but did that instead. Now that is customer service. Like always it was super easy to work with these guys. Thanks again.

Took my 2016 F 350 in for a dpf delete and 5” exhaust when they opened and they were test driving it before lunch. I pull a camper full time for work and I thought my 7.3 pulled good, until stl diesel tuned my 6.7 (with gear head tunes) Rick and his crew was very informative, professional and reasonable!!!

Had an issue on an 08 Ford 6.4 diesel. This shop was exactly what I needed. They diagnosed the issues, and suggested repairs. I questioned their suggestions, and Rick walked me through all of it. They gave me a budgeted price. I took it back in a few days later and had them do the work. I was kept informed as to some changes (you can’t see everything with a flashlight or computer). They preformed the work and stayed below budget. Awesome job guys/gals.

Great group of guys in this shop! Reasonably priced repairs. (And it doesn't have to be a diesel! �) Thanks again for taking care of my truck! I will be back!

I had a wheel bearing go out on my way to okc this morning. These guys squeezed me in and got me back on the road in less than 2 hours. Very reasonable rates and friendly service. Definitely worth the detour from the city to get my truck fixed by an actual diesel shop. Thanks for the decal too! I'll definitely stop by again.
