i was wondering if anyone could help im havin a problem with my car boosting its been fine the whole time ive had it but recently the turbo seems to stop boosting. normal driving it fine but if you boot it up its boosting ok but then when u go to the next gear the boost is severly reduced and some time wont kick in fully again unless you take it right up the revs. its like its lagging severly. the car is running a stage 1 tune. it has a full stainless exhaust, panel filter, chip, -31 actuator, relocated dump valve and its usuing a bleed valve for controlling the boost. any help would be appreciated.
