s/c pressure
when i first got my car, at idle the pressure would be around -22.5 to -25 psig. recently, at idle, my car sits at maybe -17.5 psig. i try to drive soft with my car, not really push it hard in traffic to save on gas. any ideas what would cause this?

mine is at about -20 at idle and we have about the same temps....but its wayyyy more humid down there!!! it could be weather, or it could be a small vaccume leak...but with a supercharged system im sure a vaccume leak would be apparent in other ways too

What is the problem if he can't hit full boost? Right now I'm having a problem--I'm only hitting 5 psi and the S/C sounds like it is struggling to get air to produce more boost. I've already cleaned the MAF and the Throttle Body, looked at every hose and connection. Can anyone help with this problem??
