The Mercedes-Benz CLS 500 Bi-Turbo 407hp is a 4.7L turbocharged petrol engine producing 407 BHP and 600 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 510 BHP and 820 Nm — a gain of around 103 BHP (25%) and 220 Nm (37%).
This engine scores highly for 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.
