Comparisons are calculated from our own recorded Stage 1 figures.

The Mercedes-Benz Trucks Atego 1326 256hp is a naturally aspirated unknown fuel type engine producing 256 BHP and 970 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 310 BHP and 1120 Nm — a gain of around 54 BHP (21%) and 150 Nm (15%).

This engine has limited remap suitability, with gains weighted towards peak power — the improvement is most noticeable at higher RPM. The tuning headroom is classified as moderate, 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.
