Haven't had any work done. But I stopped in to buy a used part. Ended up chatting with me for almost a hour. Very friendly, outgoing and informative.

I brought my 2006 F350 in for an oil change, leaky valve cover and a small intermittent coolant leak. They got it all done same day. Corey and Brad were friendly, professional and very knowledgeable of the 6.0 Powerstroke. They are a relatively small, but very clean shop. They can be busy at times but up front about scheduling which I appreciate. The to-do list goes on of course with this old truck.

Cory is professional and explains in detail what is going to be done and how it’s going to take place. I went in with a bad tune and he was able to get his shop to get my truck running right with a single tune at first. I then went back and did an upgrade to an ezlink shift of the fly tune and I’m beyond happy and content. All this done on a phone call on what needed or wanted done and performed on the same day of call being placed. Cory and his shop will continue to have my business and highly recommend anyone to let him take care of your vehicle.
