The Mercedes-Benz GT Black Series 4.0 Bi-Turbo 730hp is a 4.0L turbocharged petrol engine producing 730 BHP and 800 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 790 BHP and 1040 Nm — a gain of around 60 BHP (8%) and 240 Nm (30%).
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 moderate, 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.
