Stage 1 remap estimates for 26 engine variants across 6 models
Browse All Models ↓Freightliner's lineup is predominantly diesel, with 26 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 Freightliner engines in our database feature forced induction, making them excellent candidates for remapping. Across the range, Stage 1 gains typically fall between 50 and 75 BHP (averaging 52 BHP) and 136 to 322 Nm of additional torque (averaging 218 Nm). These gains come from optimising boost pressure, fuelling, and ignition timing — all within the engine's mechanical tolerances.
Freightliner engines have an average suitability score of 6.4/10, 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.
