Actuator has a vacuum/boost hose going to it yea?
what happens to the boost when you disconnect it (blanking the hose) and taking it for a run...as in is the turbo capable of making the boost when it's normally dropping to 1 bar.
wastegate definately shut properly? signs its not would be boost slow to come in...
dump valve - easy to check, pull the vacuum line off and suck on it, does it hold suction on your tongue?
got to be something stupid......
