Thanks. Did you have your WG "cracked" or fully open when making 2-3psi?
Hard to recall exactly how far I had it open but I had the rod threaded out almost all the way. It was a pretty generous opening. Am thinking there was about 3/4" clearance between the flapper and the seat.
Another thing to try for good measure. You running recirc setup or vent to atmo? If doing recirc you could put a check valve on the BOV so it stays open from vacuum. Wouldn't do that if venting to atmosphere. You don't want to start sucking unfiltered air back through it.
