Custom Cummins® Tunes Created by Mario Monette

Owner & Head Programmer

Mario High Performance Diesel

One of the leading custom programmers in the world, Mario Monette is the lead programmer and owner of MHPD Inc. For over 20 years, Mario has been building and programming diesel trucks. The proof of his expertise is in his 1988 Peterbilt 379 drag racing diesel semi which holds the world record 120.35mph.
Most shops buy and resell generic tunes from programming companies. With Mario High Performance Diesel, you get customized tunes from the programmers themselves.

Your Cummins® engine like you've never felt it before.

5 Star Review

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?

5 Star Review

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!

5 Star Review

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.
