It's proabably about 3/4 of a hole and peeking at 17psi, like i say if it was one full hole that would be around 20psi.
Its a -31 actuatuor the minimum boost it will hold is about 10psi and that is if the rod was just slipped over the wastegate arm with no preload.

Not necessarily mate, the last zvh i did i set the pre load on that garett -31 to one hole's width, also using a bleed valve it only spikes to 17-18psi but holds a good 16-17 going by the gauge, tailing off slightly towards the end of the rev range. on a standard head and cam though. Also i said it would be the amal valve plug
