Not boosting fully during quick gear changes

Afternoon!
Experiencing a wierd problem in my r at the moment. it`ll boost and hold a bar fine to red line when rev`ing from say, cruise to redline.
Sometimes though, when i change gear real quick, i.e. sprinting from 2nd to 3rd it`ll only boost up to and hold 0.8bar boost. if i let of the throttle then get back on it it`ll hold the bar fine again. does this a fair amount and i was wondering if the actuator could be getting weak on me turbo? in the past people have mentioned that i could have cracks around my waste gate but i`ve looked at it and can`t see any cracks by removing the downpipe.

anyone got any ideas?

cheers ollie

you wont see the cracks by removing the dp. it can crack around were the popet vlave seals. check and see ifyou have any boost leaks.
