The Mercedes-Benz GLS 63 AMG 585hp is a 5.5L naturally aspirated petrol engine producing 585 BHP and 760 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 635 BHP and 935 Nm — a gain of around 50 BHP (9%) and 175 Nm (23%).
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.
