Mercedes-Benz S 350d (3.0D) 286hp Remap

The Mercedes-Benz S 350d (3.0D) 286hp is a 3.0L turbocharged diesel engine producing 286 BHP and 600 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 380 BHP and 820 Nm — a gain of around 94 BHP (33%) and 220 Nm (37%).

This engine scores highly for remap suitability, with a balanced spread of gains across both power and torque — providing a noticeable improvement across the rev range. The tuning headroom is classified as high, based on the percentage gain available from the factory output.

Considerations: High tuned torque: check transmission torque capacity and service history.. Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.

Fuel economy note: economy gains unlikely at full power; depends on driving style.

All figures shown are typical estimates based on aggregated Stage 1 data for this engine variant. Actual results depend on vehicle condition, mileage, and the chosen tuning method. We recommend discussing your specific vehicle with a qualified remap professional.
