have t'd into line with gauge attached, and on a run virtually no movement on gauge throughout rev range, overboost pressure reading about a third behind target boost pressure, but once caught up is like for like, as is air intake and objective air.With vac line t in tried to see if actuator was moving and got no movement,connected direct to actuator applied vac and got "normal" movement.Had to stop at this point as the wind and rain came in with a vengeance.
