bad boost gauge?
so before i go and buy a new autometer boost gauge, i wanted to ask this question and see if my gauge is messed up or is it just something simple.
at vac. the needle is dead still, but when i start to make boost (peak around 9-10) the needle is vibrating all over. so i cant really tell if im making 8psi, 9psi, or 10psi. i have it hooked up inline with the vacuum line going to the blow off valve. could this be the issue?
i had a similar issue when i had the same gauge hooked up to my supercharger set up. that time it was directly connected to the intake.
just dont want to spend money on a gauge if thats not the issue
