Accountablity

The most professional operation I have dealt with. Mario has repaired a number of tunes by others who aren't as experienced. Mario brings to the table both professionalism and accountability. Will your tuner give you warranty?

Colin H

Best in the Biz

Simple! MHPD is the best when it comes to diesel engines! He knows his stuff completely. Had engine problems and I brought it to Mario. He told me everything that was wrong, why it was wrong and he fixed it. After, I got higher MPG and more HP from my engine with Mario's tune! I WILL NEVER GO SOMEWHERE ELSE TO GET ENGINE OR TUNING WORK DONE! HE'S THE BEST! SIMPLE AS THIS!

Bearded Express

Highly Recommend

MHPD's tunes are customized to each truck and not just a blanket tune like all of the competitors. The customer service and support is unmatched. At the end of it all, the truck makes more power, uses less fuel! Would highly recommend MHPD to anyone considering a delete.
