Assessment
The BMW 7 serie 740i 326hp is a 3.0L naturally aspirated petrol engine producing 326 BHP and 450 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 370 BHP and 520 Nm — a gain of around 44 BHP (13%) and 70 Nm (16%).
This engine has limited remap suitability, with a balanced spread of gains across both power and torque — providing a noticeable improvement across the rev range. The tuning headroom is classified as moderate, 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.
