I'd just say sod it put a tiny bit of weld on the wastegate arm only a small amount so it can be taken off, if it boosts Ok then you no its a weak actuator, then find a known good one and replace, only down side to this is it could potentially spin the turbo way past the boost it likes and kill the turbo so I'd say if you do that be careful with your right foot why you test it.
I did see some were you tested the actuator with a foot pump? Was it Ok then, when I bought my gt20 the actuator that come on that was a vacuum operated one so it had a vacuum to hold it shut, I might be way off with that one but running out of ideas tbh.
