What do most of you read on your vaccum/boost gauges in inches of Mercury (in. Hg)? At idle I see around 20. I think that's a bit low for these cars, could be a leak. Let me know, thanks guys.

 

mine reads around 18-20 usually at idle and i believe its the same with everyone elses

 

mine is also around 18-20 it will hit every once in a while 21

 

Are you sure that's not mm Hg?

 

I'm bone stock and it has sat around 18-20 at idle in neutral from day one. I even switched to a mechanical guage and it sits the same. Blown 4-banger's and OniMirage's cars sit exactly the same.

EDIT: Oops I have an Injen CAI as of last week. Been stock so long it's just automatic to say stock.

 

18-20 at idle is normal

 

Must be my old gauge was just broken then maybe. It used to sit around 12 in. Hg.
