This BMW E61 535d with a 3.0-litre twin-turbo diesel engine was prepared for power calibration. DPF and EGR control had been disabled, while the catalytic converter remained in place. Before the new file, the dyno recorded approximately 283 hp and 565 Nm.

After the software was revised, the video title lists 372 hp and 705 Nm. An inspection after the test revealed an oil leak and damage to a boost hose. The hose had a hole through which pressure was escaping.

The damaged hose was due to be replaced. The dyno result should therefore be considered alongside the boost leak found after testing; the video does not confirm that the repair was completed.
