Jason and his team saved the day. We were traveling through Cedar City and the duramax started acting up. Power Driven got me in touch with these guys and they dropped what they were doing to get me back on the road. They are experts at what they do and very polite and courteous. I’ll be sending them business any chance I get. Thanks Jason!

Jason and his team have taken such good care of me and my truck. They’re knowledgeable, honest, and have great communication.

I recently called around a few shops about an issue on my Duramax with fuel and some other work I needed on my truck. Performance Auto Customs stood out immediately—they were on top of things and got me scheduled right away. They kept me updated throughout the process, and the quality of work was excellent. I'll definitely be bringing my truck back here in the future.

Great place to go. Super busy, since there aren't many diesel shops in Cedar, but they know their stuff. Trusty diesel service.

Tried to replace the ecm on my 99 dodge when I handed them the PCM, called me said I had the wrong computer... With that sorted out all that was needed was to program and flash the truck. 2 hr process. Kept the truck overnight. I had to call them the next morning to find out that he was unsuccessful in this.(I was not charged) so I tell him to get me a price on installing a voltage regulator bypass. 8 hrs later I had not received a call. I called them, my call was not answered, I went and picked my truck up ill fix it myself, I just didn't want to jack with it. This place is a joke in my opinion. Oh and they don't "do" transmissions only Alison.
