only 13" hg at idle?

[BryanK]

hey... I installed my boost gauge the other day, and I'm worried about the vacum reading I'm getting. At idle, I consistantly get about 13" hg. I've looked around, and everyone else seems to be getting around 18" hg. I have about the first stage of mods done. The boost reads at 12 psi for the stock boost setting, which sounds right. Should I be worried?
Thanks,
BryanK

i think the normal range is usually around 17-20 Hg. if yours is at 13Hg you might have some vac. leaks. do an intake leak test and find out if there are any. I use to have around 15Hg at idle and after i found a leak at the throttle body gasket. after i fixed it i was holding around 17-18Hg.
