^ Agree.
Ultimately poor vacuum cant close the wastegate, if its not a vacuum issue, then it could be the WG arm itself is worn or not closing. Do you get any WG rattle?
Just because the vacuum system isnt leaking doesnt mean its not a vacuum problem, could also be the boost actuators which control the WG opening from the ECU. I replaced both of mine with the rest of the vacuum system and it cured my problems.
