This 2014 BMW F31 has a 1.6-litre diesel engine, an EDC17C50 control unit and an eight-speed automatic transmission. The owner requested more power and several software changes. Factory figures cited in the video are 116 hp and 260 Nm. After DPF removal but before the main power calibration, the dyno recorded 113 hp and about 271 Nm.

The DPF was removed and the ECU software adjusted to match the change. The catalytic converter remained installed. The video also mentions EGR software changes, sport display calibration and disabling the Start-Stop system.

After the power calibration, repeat dyno runs recorded 180–182 hp and 422–426 Nm. These results apply to this specific vehicle and its configuration after the work.
