The BMW G30 with a 3.0-litre diesel engine initially produced 242 hp and 556 Nm on the dynamometer. The factory figures quoted in the video are 265 hp and 620 Nm. The DPF had already been physically removed, so the engine software related to filter operation was also changed during this visit. The catalytic converter and EGR system were said to remain fitted.

After engine calibration, the dyno result was reported at around 292 hp and 700 Nm. The automatic transmission was also reprogrammed separately using xHP. The transmission changes were intended to make shifts quicker, and the selected gear is displayed to the driver in D mode.

The video also claims a 0.25-second improvement in Launch Control acceleration, but it does not show a separate 0–100 km/h measurement. That figure should therefore be treated as a stated or calculated software effect, not an independently confirmed time from this video.
