Assessment
The Mercedes-Benz C 63 AMG 476hp is a 4.0L naturally aspirated petrol engine producing 476 BHP and 700 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 570 BHP and 820 Nm — a gain of around 94 BHP (20%) and 120 Nm (17%).
This engine has limited 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 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.
