Customer Reviews

I keep getting security access code 33 and it will not tune. I purchased the truck used and I believe it is due to a previous tune that has the ECM locked or something. Very frustrated at the moment.

These guys crushed this transaction. I got the full kit with 5” exhaust. Shipping was fast, kit fits great, I’m very happy with the tune. I dropped the ball and missed adding truck info for the tune in the confirmation email, did so Saturday after install. Had the tune file Monday. Big fan, super easy install. Highly recommend.

A simple clean easy way to cap all open plug ends

Installed with no issues. Omit the short piece with a hanger bracket for 2008 2500HD GMC LMM CCSB.

Very knowledgeable people fast service and response with questions quality parts will recommend to friends or anyone who needs any of their services Scott Billets

Install went well. Everything on the exhaust when in smoothly. Customer service was great. Installed the banks ram and the kit in a weekend.

Fit like it should and sounds great

No issues & prompt delivery.

The switch works great but I am only getting 16to17 mpg thats what I was getting before and when I return it to stock it runs really rough I think the tune writer missed something on mine. It was in buy discount muffler and they have done several for me before, the 07 they done for me gets 28 to 30 mpg they also said they missed something and they have been a dealer for years for bully dog.

Very easy to use and customer service is readily available!

Everything is working great thank you guys!

The kit worked as I expected and was straight forward. I just recommend two people when installing as it’s easier. My only gripe is the packaging was in rough shape like it’s been used quite a bit.
