This BMW E46 has a 3.0-litre diesel engine and had already received hardware changes: a larger turbocharger and intercooler, along with exhaust modifications. The fuel system remained in its original configuration.

Before the ECU software was adjusted, the car was tested on the dyno. With the hardware changes already installed but before the new ECU calibration, it recorded 202 hp and 445 Nm.

The engine calibration was then adapted to the vehicle's setup and another dyno run was carried out. The video reports torque approaching 600 Nm and quicker turbocharger response. It does not provide a clear final horsepower figure.
