    I would say just T into any of the lines off the intake Mani. Its too easy to cut one of the vacuum lines and T it to your Guage.

    Tee it off of the nipple on your throttle body.

    I recommend teeing off the afpr lines and routing the line through the boot for the steering column. If you do this you may want to zip tie the line to a harness underneath the steering wheel so it doesnt get in the way of the pedals if its too long. I can help with any electrical wiring too since i basicly had to figure it out on my own for a gauge pillar so just ask and i can take pics too.

    Are you sure that wasn't vacuum? How much psi are you running just curious

    It will be negative because of vacuum. At idle it should be negative always. If it isn't, you tapped into something that doesn't give correct vacuum readings, which is not good.

    For ex. On my 4g63t it sits at -18 at idle

    I switched to the throttle body hose and when at full boost it just said -10(10 vacuum whatever). Is that major boost leak somewhere? I still here the big whoosh out of the BOV.

    Idle at 19 vacuum

    Get a vid of the car doing a WOT pull from the out side and one of your gauge.

    I have mine hooked up to the throttle body and works fine. Is it on the "p" port? You can let it have its own line to the intake. Or T it with the fpr.

    This may be a stupid question but the boost will still recognize boost when in neutral right(have mine on jacks right now).

    It should read vacum at idle and will read boost when the motor is under a load.
