Having a problem with boost fluctuations after turbo transition at about 5000 rpm and up. It will fluctuate +/- 1 psi of the target boost. It does not happen when the PFC duty cycles are turned down all the way and the WG spring limits boost at around 7-8psi.

Does any one have any clue what this could be??? Anyone ever experience anything similar with the stock boost control and a PFC??

Searched already and found nothing, already ran all of the factory trouble shooting on the WG actuator, solenoid, and the vacuum lines.

Any help would be greatly appreciated, as running around at 8psi SUCKS!
