Copperhead Diesel Performance

Great time dealing with the people over here! They got the issue resolved that 3 other shops were scratching there head about. Even when the issue wasn't resolved and I had to bring the truck back they made it right with the repairs and squeezed me back in the schedule to get it done as soon as possible. Now that those repairs are out of the way I can't wait to go with them again when I get around to some basic performance mods!

Great service! Had them do an EFI live tune on my 2002 LB7 and it runs amazing! Great fuel economy and a lot of power for driving and towing. Only place I will trust with my truck.

As a auto repair shop as well diesel is not what we work on every day. So I took my 2013 duramax lml there crank no start died in parking lot..... FML Sean was on the phone super busy so he had his tech walk out and check it for me. Decided hell i am here why not have them fix it, they we super nice and took the time to look at it when they were clearly vary busy. Sean walks out 3 hand tools tinkered with it no more then 3 min had it runing told me what was wrong. Took it back to my shop put the part on runs perfect..... If i could give 10 stars i would this is the kind of place where the customer comes first they have gained a life long customer. Thank you Brandon and Sean you guys are great i wish the world had more people like you guys.

Thanks to Sean at Copperhead Diesel Performance for my new exhaust and other performance mods. My Duramax is nice and quiet just like I wanted. I wasn't too comfortable with changing my exhaust because I didn't want a loud pipe. I was told it would be very quiet and look almost like stock. They delivered as promised!!!! Sean is extremely knowledgable and willing to answer any questions I had. (And I had a lot of questions) Their service and workmanship is top notch! Can't wait to tow again.
