My boost gauge is reading 18-19 in HG with the idle set at a 956 rpm is this normal or should it be higher. Does this indicate a vacuum leak? Thanks guys.

 

mine is at 15ish at idle.

 

are you cammed? I feel like that is really low.

 

normal. Mine reads 19-20 at Idle and 15-16 with AC on high.

 

mine is 18 - 20 idle, 16 or so with ac on

 

ok thats where im at so i guess im good. Thanks for the input

 

yeah 18-20 seems right..

 

mines 20 and 17 with ac on

 

Actually I might have a boost leak.

 

so 35 is a little high?

 

well my boost gauge is messed up but im at 20ish on it but i idle at like 1100 im not sure if thats normal

 

Yeah I peak at 20ish to. but at idle mine is also at 11ish. I bought the boost leak tester from boostpro.net to see if I have a leak. i'll keep you posted

 

i vacuum at about 30-35 also. is that high?

 

I would think its high. Check the gauge. I'll be doing a few test of my own, to see if my gauge is accurate. Mine reads between 11-12 vacuum, and a little over 20psi at peak boost, then it tapers off to like 15-16psi by redline. No boost controller. From what I hear 18-19 vacuum is normal. So mine is to low and yours is to high.

 

im at 16 at 900rpm
