The 2.4D in the P2 and P3 are nominally identical, although there are a few differences (pipework, etc). I would expect the boost pressure to be the same.

Yeah my 2006 2.4d has the stepper control turbo yet the d3 is vac solenoid with an electronic position sensor on the rod. Filter is clear, mine seems to be more ecu related (requested too high)
