This BMW F01 740i with a 3.0-litre twin-turbo petrol engine was prepared for a Stage 1 calibration. The video gives the original figures as 330 hp and 450 Nm. The catalytic converters, sensors and remaining emissions equipment stayed in the vehicle’s original configuration.

The engine control software was read and written in Bench mode. After the Stage 1 calibration, the dynamometer showed approximately 380 hp and 508–510 Nm, around 50 hp and 58–60 Nm above the stated original figures.

The dyno test made it possible to assess the change after the software was written. These figures describe this particular car and its condition; they are not a guaranteed result for every vehicle of the same model.
