For drivers and fleets seeking reliable semi diesel engine tuning and parts, MHPD sets the industry standard in clean, data-driven performance.
Our emissions-compliant tuning utilizes dyno testing and tuning for unmatched precision, ensuring compliance with regulations. Highway trucks require precise tuning, and ours is based on diagnostics, dyno testing, and thorough mechanical checks.
With decades of diesel expertise and full ECM and parts support, we enhance power, torque, drivability, and fuel efficiency while extending the life of your engine. At MHPD, performance is engineered; we never guess.
What We Tune And How We Deliver
MHPD delivers heavy-duty tuning across North America, focusing on Class 8 highway trucks, commercial fleets, on- and off-highway vehicles, as well as industrial and agricultural applications. We lead the industry, elevating your engines.
Tuning from the MHPD team is available in multiple ways:
- In-shop at Edmonton and Acheson: Service is typically completed within a day for a quick turnaround and minimal downtime.
- Remotely via our secured dealer network: Service takes just a few hours, making it perfect for busy fleets that need efficiency.
We tune almost every diesel platform, including Cummins, Detroit, PACCAR, CAT, and more. We mainly exclude Volvo/Mack and some Isuzu and Hino engines.
Tuning Is Not A Substitute For Mechanical Repairs
Tuning optimizes combustion, drivability, and efficiency but does not fix mechanical problems. Issues often stem from low or unstable fuel pressure, clogged filters, coolant leaks, electrical faults, or faulty ECMs, not the tuning.
Semi diesel engine tuning can’t fix a flat tire, so we ensure all mechanical systems are working properly before tuning. Every truck receives MHPD’s pre-tuning checklist, which includes fuel pressure, leaks, ECM communication, and sensor data. We take every precaution for a tuning-ready engine.
Our thorough checklist is one reason we can confidently say, “We don’t blow up engines!”
Honesty First: When We Refuse to Tune
Not every truck benefits from a tune. We will tell you directly. If your semi-diesel engine experiences mechanical failures, damage to the emissions system, or unstable wiring or injectors, tuning will not help and could exacerbate the issues.
Our goal is to enhance your engine’s performance, not to mask mechanical issues. We value honesty, and our customers appreciate direct communication. Addressing the core problems will help you save time, money, and reduce downtime.
Diesel Engine Tuning And Parts: ECM, Sensors, And A Lifetime Warranty
When you call about tuning issues, most causes are mechanical. Burned or replaced ECMs without transferred tunes are common. We’ll help you get the right parts, program replacement ECMs, and transfer tunes. We help protect your diesel engine from surprises.
When you tune your diesel engine at MHPD, you receive a lifetime warranty. If it runs well today, it will continue to run well tomorrow. We’ll support your tune for as long as you own the truck, including updates, adjustments, and post-service help.
