OH crap. SO, then the accelerator is pressed down an open. Darn. OK, that being said the number used air being sucked in through the intake valves then? IN which case they're about right? I figure the pressure necessary to suck air through the intake with the tb closed is fairly high, with open TB it's another 40-60 psi I am missing. Just shooting at the dark now.
Probably do it again tomorrow.
