Ok, I just bought a boost gauge and im having trouble getting it hooked up to the right vacuum line, I know you are supposed to tee of the FPR vacuum line but that isn't where i personally would want to do it, ive heard that this can sometimes lean your motor out. I DEF don't want that. Can anyone tell me any other place i can tee off of to get a correct boost reading?? Oh yeah and the motor is a sr20det. reps for any help.

Thanks guys.

ANY vaccum line coming off of intake manifold...

wastegate air line (if external)

99% of people do it through the FPR... but any vacuum hose on the intake manifold side should work. Never had a SR20 though. Then there's a hole on the firewall near one of the foot pedals where you can get the hose through.

Which one is that?? Is that the one right up under the throttle body hooking in to the BOV??

I think those canister lines have check valves in them to prevent reverse flow. Just tee the FPR and be done y0.
