Alfa Romeo 159 1.9 JTDm 115hp Remap

The Alfa Romeo 159 1.9 JTDm 115hp is a 1.9L turbocharged diesel engine producing 115 BHP and 275 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 145 BHP and 350 Nm — a gain of around 30 BHP (26%) and 75 Nm (27%).

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.
