Assessment
The BMW 6 serie 650ci 367hp is a 4.8L naturally aspirated petrol engine producing 367 BHP and 490 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 390 BHP and 525 Nm — a gain of around 23 BHP (6%) and 35 Nm (7%).
This engine has limited remap suitability, though the available headroom is limited, so gains are modest compared to higher-output variants. 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 5/6-speed automatics (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.
