This BMW X5, with a 3.0-litre diesel engine and a single turbocharger, was measured on a dynamometer before tuning. The video gives factory figures of 218 hp and 500 Nm, while the car's initial run recorded 213 hp and 468 Nm.

After the initial check, the engine control unit was recalibrated, including adjustments to the EGR-related settings. The car was then tested on the dynamometer again.

The work considered more than peak output: engine pickup and the shape of the torque curve were also assessed. The video shows a post-programming test, but an exact final power figure is not included here.
