This 2007 BMW E65 with a 3.0-litre diesel engine was first tested on a dyno. The DPF had already been physically removed and the EGR valve blanked, but the engine software had not yet been adapted to those changes. The initial run recorded 236 hp and 515 Nm.

A mild Stage 1 calibration was then carried out, with the ECU also adapted for the DPF and EGR changes. The final run recorded 257 hp and 625 Nm. The video title lists factory figures of 231 hp and 500 Nm; the initial dyno result is a separate reading taken before the ECU calibration.
