Gentlemen. I'm on the side of the road , going nowhere as I have no boost, can do 40 kmh max , and egts are out of control. Car was running flawlessly and then it Happened fairly suddenly.

Popping the bonnet this boost controller was just flopping around , it must have dropped out of secure spot after dyno I had on Monday.

Re secured it & adjusting it , turning it, does absolutely nothing no matter how many turns either way ...
Is there a trick to these I am not aware of ???
Either I'm doing it wrong or it got damaged internally as it flopped around and now it's stuffed.
