No problem with these guys. they did a complete top end on my 06 duramax, exhaust, cold air and tuner...I roll down the highway at 75mph and get 25 to 28 mpg. Some folks need to lighten up. Especially the ones that don't know what they are talking about.

I am from Phoenix Az. I called with a problem with my Rv. They usually do not service RVs but made an exception for my situation. They are very courteous and quickly troubleshot and repaired my Chevy 454 engine problems all in about half a day. Thank you for saving our vacation.
