Fiat Croma 1.9 JTDm 150hp Remap

The Fiat Croma 1.9 JTDm 150hp is a 1.9L turbocharged diesel engine producing 150 BHP and 305 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 185 BHP and 385 Nm — a gain of around 35 BHP (23%) and 80 Nm (26%).

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.
