vacuum

[BoostJunki3]

hey guys my boost gauge is at -21 at idle and -23 while cruising why is it so low? am i just the only 3800 with out a vac leak? :th_laugh-lol2:

Your gauge is probably inaccurate. What do you mean cruising? What speed? I have 20in hg at idle and cruising on the highway at 75 generally see 10in hg.

when i let off the gas around 40 mph i see 23.....it is a glow**** lol....i read 21in hg at idle

sounds okay to me. what about when youre actually on the gas. mine was around 10 in/hg cruising.

mine sits at 10in/hg cruising and if I let off the gas and cost it will drop to 21-23.
