The Alfa Romeo 147 1.9 JTD 100hp is a 1.9L turbocharged diesel engine producing 100 BHP and 200 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 135 BHP and 265 Nm — a gain of around 35 BHP (35%) and 65 Nm (32%).
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.

Fuel economy note: economy gains unlikely at full power; depends on driving style.
