Customized tuning is an investment that pays off quickly. While upfront costs are higher, your Cummins engine will run smoother and more efficiently.
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.
Not pulling off the line like you used to? You've come to the right place. Optimizing Cummins diesel engines can be difficult and expensive with stock EGRs DPFs, and other emissions controls. We know that whether you’re an owner-operator or a fleet manager, improving engine efficiency is always on your to-do list.
We make sure each and every diesel engine we work on is customized to fit your specific truck. No more error codes. No more lights. Just more power, better fuel efficiency, and peace of mind.

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?
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!
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.
Mario and his team are very professional and great to deal with. I look forward to dealing with them for many more years. Keep up the great work!!!
