This BMW E60 525d with a 2.5-litre diesel engine and an EDC16C35 control unit came in for power calibration. The video says the engine and catalytic converter remained in standard configuration, while DPF and EGR control were changed.

The video title lists gains of 68 hp and 187 Nm. The spoken section also gives a final result of approximately 285 hp and 588 Nm, and notes a small amount of black smoke at high load.

The gains in the title and spoken section do not fully match, so they should not be treated as an exact calculation from the same baseline measurement. No additional turbo or internal engine upgrades are mentioned.
