Assessment
The BMW 5 serie 550i 449hp is a 4.4L naturally aspirated petrol engine producing 449 BHP and 650 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 470 BHP and 700 Nm — a gain of around 21 BHP (5%) and 50 Nm (8%).
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.
