Boost gage on 92 SSEI
Hey i was wondering if it was normal that my boost gage stays at -70 when i'm not accelerating....right when i accelerate it goes up as i go further down on the pedal obviously....but is it normal that it idles at -70 ?
If not what could cause that?

You are reading manifold vacuum at idle, just like a non-supercharged car. Mid-throttle should read about zero, and wide open throttle (in gear) should read about 8-9 psi on US cars and about 3/4 scale on 
cars with stock pulleys.
