The Mercedes-Benz GLS 500 (4.7 V8 TT) 455hp is a 4.7L naturally aspirated petrol engine producing 455 BHP and 700 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 500 BHP and 850 Nm — a gain of around 45 BHP (10%) and 150 Nm (21%).
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.
