Abit of good timing if the same as 4he1t just pulled it apart a 10mm nut and
slot in shaft about middle in pic so I would say no :(

Yep, whole boost compensator housing unbolts and pulls off. Just be careful with the pushrod inside.

Thanks for help, it was just the gasket holding on, i taped a kitchen knife carefully down into the gasket and the housing popped off, there was 2 small holes in the diaphragm, hopefully that is where i am losing power! Rang looking for new diaphragm $50 plus $10 for gasket.
