Boost gauage help

i just put in an apex’i boost gauge by myself.
everything reads well so as the lighting.
however, the gauge never goes down below 0
that means i can not read the vacum…
anyone know what the problem is??
its s14 blacktop sr. should be running @ 0.4-0.5bar at stock 7psi…

thanks

You probably hooked it up to the hot pipe right after the turbo. Hook it up somewhere on or near the throttle body.

What is a good place on throttle body to tee of off, i know that some people use fpr, but i wouldnt.

fuel pressure regulator, i have mine t’d off it, works fine. but any of those vacuum lines comin from the throttle body should be good
