I was wondering what our vacuum readings are during idle, during WOT & after WOT. Can someone chime in? I know it’s near 0 for idle due to the valvetronic but I hear during a pull it changes.

high rpm lift, you might see a momentary 8 inches of mercury, no more than 10. idle, 2-ish inches.

example at 3000 rpm. sorry for out of focus, major ticks are at +5 psi and -10 in.Hg
