boost issue

[catchmeifyoucan01]

just a quick queston ive got my boost set to 1 bar and it use to hold all the way but recently it hits 1 bar and as i go through the rev range it drops to 12.5 psi ish! any ideas been told that it sounds like a weak actuator any ideas??

weak actuator,cracked wastegate housing,setting's need changing on your boost controller?

I would of thought weak actuator aswell, although have you checked the exhaust turbo gaskets for any leaks, could cause a drop on boost, certainly did on my car when mine were old and past it.
