Assessment

The Renault Trucks Kerax 412hp is a naturally aspirated unknown fuel type engine producing 412 BHP and 1870 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 490 BHP and 2300 Nm — a gain of around 78 BHP (19%) and 430 Nm (23%).

This engine has moderate remap suitability, with a balanced spread of gains across both power and torque — providing a noticeable improvement across the rev range. The tuning headroom is classified as high, based on the percentage gain available from the factory output.

Considerations: Naturally aspirated engine: gains are usually limited; results vary widely.. Unusually high gain for NA engine: treat as an estimate and verify against the exact engine variant.. High tuned torque: check transmission torque capacity and service history.

All figures shown are typical estimates based on aggregated Stage 1 data for this engine variant. Actual results depend on vehicle condition, mileage, and the chosen tuning method. We recommend discussing your specific vehicle with a qualified remap professional.
