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.
