Mario High Performance Diesel

Custom ECM Tuning

What is ECM tuning?

The short answer: ECM tuning is editing the electronic system that controls your engine.

The longer answer: Your engine's system is controlled by an ECM (electronic control module) that tells it how much fuel to push, when to fire, and a bunch of other things. By editing the software, MHPD can give your diesel truck more power, a better response time and lower fuel consumption. These optimizations make your engine runner cleaner and more smoothly by perfecting the combustion process and outputting cleaner exhaust, giving you a longer overall engine lifespan. With our tunes, you can reduce annual maintenance cost and save enough on fuel to pay back tuning costs within the first year.
