Assessment
The BMW X5 xDrive40d 340hp is a 3.0L naturally aspirated diesel mhev engine producing 340 BHP and 700 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 380 BHP and 750 Nm — a gain of around 40 BHP (12%) and 50 Nm (7%).
This engine has limited remap suitability, with gains weighted towards peak power — the improvement is most noticeable at higher RPM. The tuning headroom is classified as limited, based on the percentage gain available from the factory output.
From a technical perspective, the transmission is many variants use zf 8-speed automatic (where fitted); manuals also exist. at this torque level, transmission and driveline servicing history becomes especially important..
Considerations: Naturally aspirated engine: gains are usually limited; results vary widely.. High tuned torque: check transmission torque capacity and service history.
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.
