Assessment
The Mercedes-Benz GT 4.0 - 476hp is a 4.0L naturally aspirated petrol engine producing 476 BHP and 630 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 575 BHP and 820 Nm — a gain of around 99 BHP (21%) and 190 Nm (30%).
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.
