The Mercedes-Benz B 180 CDI 109hp is a 2.0L turbocharged diesel engine producing 109 BHP and 250 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 170 BHP and 360 Nm — a gain of around 61 BHP (56%) and 110 Nm (44%).
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: economy gains unlikely at full power; depends on driving style.
