The Mercedes-Benz CLS 63 AMG Bi-Turbo 525hp is a 5.5L turbocharged petrol engine producing 525 BHP and 700 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 620 BHP and 900 Nm — a gain of around 95 BHP (18%) and 200 Nm (29%).
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: Turbo petrol: fuel quality and cooling can influence repeatable performance.. High tuned torque: check transmission torque capacity and service history.. Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.
