when i first installed my 16g my vac pressure @ idle was 20-22
it was fine, i turned the boost up to 14 psi b/c i was running pretty rich. one day one of my hose clamps slipped off so i had to drive all the way home w/ my car running funny. ever since i hooked it all back i'm my vac @ idle is 16-17 and my spool up is around 4k which is rediculous.

this can all come from a leak somewhere ? possibly my bov screw being backed too far out ? what else can cause this besides a leak ?
