Assessment
The BMW Z4 3.0si 265hp is a 3.0L naturally aspirated petrol engine producing 265 BHP and 315 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 280 BHP and 360 Nm — a gain of around 15 BHP (6%) and 45 Nm (14%).
This engine has limited remap suitability, with gains weighted towards torque — you will notice the difference most strongly in mid-range pulling power and in-gear acceleration. 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..
Considerations: Naturally aspirated engine: gains are usually limited; results vary widely.
