Assessment

The Mercedes-Benz AMG GT 4-door Coupe 43 AMG 3.0 367hp is a 3.0L naturally aspirated petrol mhev engine producing 367 BHP and 500 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 420 BHP and 620 Nm — a gain of around 53 BHP (14%) and 120 Nm (24%).

This engine has limited 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 moderate, based on the percentage gain available from the factory output.

Considerations: Naturally aspirated engine: gains are usually limited; results vary widely.. 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.
