This BMW with a 3.0-litre diesel engine had a modified turbocharger with a larger compressor section. The video says that most of the remaining setup was standard; the DPF was not fitted and the EGR system had been disconnected. Before the new engine calibration, the dynamometer showed about 240 hp and 576 Nm, compared with stated original figures of 218 hp and 500 Nm.

A new calibration was then written to the engine control unit and the car was tested again. The video confirms that a power test took place, but the final power and torque figures are not clear enough to report as exact values.

Possible future upgrades were also discussed, including a larger intercooler and intake changes to improve airflow. These were plans for later work, not modifications completed in this video.
