The Mercedes-Benz X-Klasse 350d 258hp is a 3.0L turbocharged diesel engine producing 258 BHP and 550 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 290 BHP and 690 Nm — a gain of around 32 BHP (12%) and 140 Nm (25%).
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: 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: possible improvement with conservative driving.
