Your next steps for custom ECM tuning

We connect to your ECM

Depending on your engine, we'll either have you pull out your ECM and either bring it to us in person or send it in the mail — OR we'll just get you to plug in and access remotely. We accept shipping from anywhere in the world.


We tune your engine

Either through TeamViewer or in-person, we'll flash your truck and run it with the optimized software. If done remotely, this step requires some work on your end. Don't worry, we'll walk you through it.


You get more power

...and more torque, and better fuel efficiency. Basically, we make sure your engine is optimized to perform to its maximum capacity while extending its overall life.

"The tunes MHPD lays down are top notch. These tunes aren’t your typical tunes the competitors give out. I’ve used other tunes before and was never sure of what I was getting. Mario High Performance Diesel tunes are designed for your application — not just some tune out of a box that everyone gets. By far the best MPG and torque you can get."
