Mercedes-Benz E 63 AMG 558hp Remap

The Mercedes-Benz E 63 AMG 558hp is a 5.5L naturally aspirated petrol engine producing 558 BHP and 720 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 685 BHP and 1100 Nm — a gain of around 127 BHP (23%) and 380 Nm (53%).

This engine has moderate remap suitability, with gains weighted towards torque — you will notice the difference most strongly in mid-range pulling power and in-gear acceleration. 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.. Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.

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.
