This BMW E46 had been converted from petrol to diesel and prepared for drifting. The video says the turbocharger, pump and injectors remained standard, while the EGR system was disabled. Before calibration, the dynamometer showed 118 hp and 338 Nm.

After the software change, the car reached approximately 273 hp and 651 Nm, as stated in the video title. A further torque adjustment was also tried but not kept: the previous calibration was restored as the preferred result for the existing setup.

The video notes that more power would require mechanical upgrades, such as changes to the pump and injectors. Those components were not replaced during this work.
