boost question

92 eclipse gst when the car is at idle in neutral what should the vac read on the boost gauge becuz mine is reading 12

as far as i know, it can be different for each car. my 2g usually runs about .5 bar (~7.35 psi) at idle and .8 bar on deceleration.

I've read a few posts on this in the past. It does seem to be altitude dependant from what I've read. I personally sit at 18vac at idle. Without checking posts It seems to me 20-16 was average. 12 seems a bit low, might want to check for leaks. Do a search if you'd like a more definate answer.

12 is low for stock cams, run a pressure test and check for leaks. Are you having any operational issues? idle surge, lost of power....

Spec is about 18. Check your tubing for kinks and/or collapsing. And, where did you tap for the vacuum?

i taped in from the p line in the throttle body
i just bought the car it holds idle pretty well im not very familar with the turbo cars yet
i checked my boost gauge line no kinks and i know there is no leaks in that line i tested it with my vac pump

Don't tap at the throttle, tap at the line coming off the front side of the manifold plenum, straight out from the driver's nose.

where exactly? is it the vacum hoses right by the brake booster and master cylinder?
and what color line do i tap in?
