The Nissan Primastar 2.5 DCi 146hp is a 2.5L turbocharged diesel engine producing 146 BHP and 320 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 172 BHP and 405 Nm — a gain of around 26 BHP (18%) and 85 Nm (27%).
This engine has moderate remap suitability, with gains weighted towards torque — you will notice the difference most strongly in mid-range pulling power and in-gear acceleration. The tuning headroom is classified as high, based on the percentage gain available from the factory output.
Considerations: High tuned torque: check transmission torque capacity and service history.. 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.
