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.
Mr.Diesel is an excellent shop everybody their are loyal they are not out to screw anyone over my 2000 dodge cummins got hit 3 weeks ago and the axle is bent they are doing everything to find me an axle and in the mean time the owner is letting me drive his own personal vehicle I don't know any other shop that would take care of their customers like the guys at Mr.Diesel
Great Customer service, work is well done. I know where I will be taking my diesel truck from now on.
