I don't know if this applies to the superturbo or any other turbo'd car but I thought I'd share my experience with you. We're always saying we need more hands on information on the forum so here goes.
My dad was complaining that his turbo didn't seem to be doing much and his car was generally slow and crap.
We checked the wastegate actuator and that was fully adjusted as high as possible (on the nuts on the rod that goes to the wastegate)
All I know about turbos is what I've read. Anyway I decided to unbolt the mounts to move the rod separately to see if maybe the wastegate was jammed open (bypassing turbo) as the car had been sat for 6 months previously.
It was fine but it was here I noticed that you could lift the actuator about another 10mm. I decided to stick a washer under the mounting plate to lift the actuator up and close the wastegate. took it for a run, slight improvement but still not great. Came back, added another washer lifting the whole unit up around 3mm. Now it runs perfect, acceleration is much better and the turbo still cuts out at the higher RPM.
I may have got some of the terms wrong here, I'm not a turbo mechanic just thought this may help someone.
However I will not be held responsible for any damage caused to your engine, run a boost gauge to make sure you're not gunna blow your rings or melt anything.
