rudefyet Posted March 12, 2004 Report Share Posted March 12, 2004 What should the boost gauge read at idle? Because i sat in the tgp i'm looking at and had in park...and revved the engine...the boost gauge moves quite a bit but it's reading a negative # when idling...i thought the boost gauge showed PSI...so isn't negative PSI impossible? Sorry...just a little over my head here...anyone can explain it to me...then smack me around a bit Quote Link to comment Share on other sites More sharing options...
RareGMFan Posted March 12, 2004 Report Share Posted March 12, 2004 No, it should be in the negative till it builds boost (for which, you'll need to be moving because in park the rev limiter won't allow you to get up high enough to build boost). Until it boosts, it's in vacuum mode, thus the negative status. *Proceeds to smack rudy around a bit* Quote Link to comment Share on other sites More sharing options...

Ok clears that up Like a hard drive, when we are first born/start up, our brains empty, but a smart man is one who wants to fill it with good info We all start at the same place till we ask or read it.
