BMW E60 2.5D — DPF removal and power calibration
DPF removal, MAF software changes and dyno testing on a BMW E60 2.5D. The reported result after tuning is 295 hp and 625 Nm.
This 2009 BMW E60 has a 2.5-litre diesel engine and arrived with a DPF warning and mass airflow sensor faults. The factory figures cited in the video are 197 hp and 400 Nm. Before the power calibration, after DPF removal and the related ECU changes, the dyno recorded 228 hp and 481 Nm.
As part of the work, the DPF was removed and the ECU software adjusted. The owner chose to leave the EGR system operational for now; the intake manifold flaps also remained installed.
The video reports 295 hp and 625 Nm after the power calibration. The dyno run was performed in fifth gear. These figures apply to the vehicle after the described changes, not to a standard factory configuration.
