So heres the problem: when I start my car up my boost gauge says I'm at about -5.6 pounds of boost, however when I start to drive the boost drops to about -7 to -8 pounds of boost, off throttle obviously. Later in the drive at idle, out of gear I'll be at about -7 pounds of boost, yet when I'm driving (at any speed) I'll be at - 9 pounds of boost, which also seems a bit low to me so I think I might have a boost leak. Anywho what I'm wondering is why does my boost drop off from idle to off throttle driving, then why is my boost even lower later in the drive. Also peak boost drops off at the same rate throughout the drive.

 

Bump. Any ideas?

 

re-bump, no one?
