Autometer Boost gauges...are they usually Off a psi. or Over a psi.??

It could be either. It could also be dead on. Pay attention to where it rests in the zero range and that'll basically tell you how much it might be off. Does that make sense? Because in theory it would sit in the middle of zero. My brother's gauge wiggles around a tiny bit in zero, but when boost comes it's actually perfectly accurate with the BLITZ SBC-ID (or whatever) boost controller he has on his 300ZX 2+2 (yes, it's TT).
