ok i installed my boost guage like a month ago and when the car is off it sits at -3. and at WOT it is at -3 so it is off. but at idle it is right at -20 where it need s to be. can i fix this or do i need to buy a new one?

pretty sure you're going to need a new one. I don't think it's possible to re-calibrate it.

Sounds like you hooked it up to a line that only sees vacuum plus its off a tad.

i hooked it to the trottle body. i wont see bost as my turbo is not hooked up yet,
