Mack's lineup is predominantly diesel, with 34 engine variants in our database. Diesel engines are among the best candidates for ECU remapping — modern common-rail turbo diesels routinely see significant power and torque improvements from a Stage 1 tune.
Around 100% of Mack engines in our database feature forced induction, making them excellent candidates for remapping. Across the range, Stage 1 gains typically fall between 45 and 75 BHP (averaging 58 BHP) and 54 to 391 Nm of additional torque (averaging 276 Nm). These gains come from optimising boost pressure, fuelling, and ignition timing — all within the engine's mechanical tolerances.
Mack engines have an average suitability score of 6.7/10, indicating good potential for Stage 1 remapping. As always, results vary by engine — check individual suitability scores to find the best candidates in the range.
A Stage 1 ECU remap optimises your Mack's factory software to unlock its full potential — no hardware changes required. Here are the typical gains across the range.
