Mercedes-Benz Sprinter 212/312 CDI 122hp Remap

The Mercedes-Benz Sprinter 212/312 CDI 122hp is a 2.9L turbocharged diesel engine producing 122 BHP and 280 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 150 BHP and 360 Nm — a gain of around 28 BHP (23%) and 80 Nm (29%).

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: Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.. Older diesel: injector, turbo and intake condition can affect results; ensure maintenance is up to date.

Fuel economy note: possible improvement with conservative driving.
