Intake manifold pressure gauge question

i was looking at this gauge for my boosted Z and i'm curious why is range only up to 2PSI if i'm putting out 9psi at compressor?

That's not a boost gauge. Its a mani pressure gauge used for vacuum and not positive pressure.

Yea i know but i thought that intake manifold pressure would be positive pressure at least close to my boost pressure? since compressor is feeding directly to intake?

That gauge is for a NA engine.

If you want a Defi this would be the one. They call it the red racer series or something like that.
