Assessment
The BMW 3 serie 330D 245hp is a 3.0L turbocharged diesel engine producing 245 BHP and 520 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 300 BHP and 600 Nm — a gain of around 55 BHP (22%) and 80 Nm (15%).
This engine has moderate remap suitability, with gains weighted towards peak power — the improvement is most noticeable at higher RPM. The tuning headroom is classified as moderate, based on the percentage gain available from the factory output.
From a technical perspective, the ECU is typically a Bosch EDC16 (likely), and the transmission is many variants use zf 5/6-speed automatics (where fitted); manuals also exist. at this torque level, transmission and driveline servicing history becomes especially important..
Considerations: High tuned torque: check transmission torque capacity and service history.. Older diesel: injector, turbo and intake condition can affect results; ensure maintenance is up to date.
Fuel economy note: possible improvement with conservative driving.
All figures shown are typical estimates based on aggregated Stage 1 data for this engine variant. Actual results depend on vehicle condition, mileage, and the chosen tuning method. We recommend discussing your specific vehicle with a qualified remap professional.
