MP7 & MP8 Engine Power Tuning Fuel Economy MPG Increase

Increase your fuel economy by 0.8-1.2 mpg on average & add an additional 60-120HP! Your engine will gain both HP and torque across the entire RPM band.

This boosts low-end torque to reduce downshifting and turbo lag. By spooling the turbo quicker, you'll build more power in the lower RPM range, reducing the need to downshift and keeping the engine out of higher RPM ranges—which translates to better fuel economy.

Option 1 - Mack ECU Re- Flash Service

(2013/2014 is a split year for ECM models. The easiest way to determine if you need the 2008-2013.5 unit is to check your diagnostic connector under the dash. If it's round, you need the 2008-2013.5 HDT-MackPM unit. If it's rectangular, you need the HDT-Mack14+ unit.)

How It Works

This unit plugs into your engine computer and controls injector timing and fuel quantities, improving throttle response and lowering the torque curve by spooling the turbocharger faster.

Increase hill-pulling speed, decrease downshifts, and start saving money today!

Why Your MP7 / MP8 Deserves Better Than Stock Performance?

Your Mack is engineered for excellence, but ships from the factory with conservative settings designed to meet regulatory requirements—not to maximize YOUR profitability or operational efficiency. That means you're operating at a fraction of your engine's true capability, leaving money on the table with every mile.
Our plug-and-play tuner module changes everything.

 

Dramatically Increased Power & Torque

Experience a substantial boost in performance with 40-100 additional horsepower and up to 350 lb-ft of extra torque—power gains that translate directly to operational advantages:

- Enhanced acceleration that reduces trip times and improves schedule adherence

- Improved hill-climbing ability that maintains consistent speeds on grades without downshifting

- Better load management for more efficient hauling and reduced driver fatigue

- Noticeable performance gains that improve fleet productivity from day one

Whether you're managing a regional fleet or running your own truck across state lines, the extra power translates to measurable advantages: faster deliveries, better on-time performance, and improved driver satisfaction.

 

Significant Fuel Economy Improvements

This is where our plug-and-play tuner delivers immediate, measurable ROI. The module optimizes fuel injection timing, boost pressure, and combustion efficiency to squeeze more miles from every gallon:

- 10-18% fuel economy gains depending on driving conditions and load

- $3,000-$8,000+ annual fuel savings per truck at typical mileage and fuel prices

- Rapid payback period—often 3-6 months for high-mileage operations

- Compounding savings for fleet operators managing multiple vehicles

- Improved profit margins that directly impact your bottom line

For owner-operators running 100,000+ miles annually, these fuel savings represent genuine income growth. Fleet managers see these improvements multiply across entire operations, creating substantial annual savings that flow directly to profitability.
