This BMW received an individual engine control calibration and was measured on a dynamometer. The technician states that the car had been producing about 186 hp before the work; the dyno reading after calibration was 282 hp. The video title reports gains of approximately 100 hp and 250 Nm, while the spoken portion does not clearly confirm an absolute final torque figure.

Data logs and engine parameters were checked before and after calibration, including temperatures, turbo pressure and fuel-system readings. The owner was present during the work. The calibration at higher engine speeds was adjusted to control smoke: the video shows no pronounced black smoke under full load, although a slight grey haze is mentioned.

The recording notes that the exhaust system had been modified: a downpipe was fitted, the catalytic converter and DPF were absent, and only a rear resonator remained. The dyno result therefore describes this specific vehicle configuration and should not be treated as a direct result for a BMW with a fully standard exhaust system.
