BMW 3 Series 340i Performance Package 360hp Remap

The BMW 3 serie 340i Performance Package 360hp is a 3.0L naturally aspirated petrol engine producing 360 BHP and 500 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 400 BHP and 580 Nm — a gain of around 40 BHP (11%) and 80 Nm (16%).

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 moderate, 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.
