when fitting a 3 bar map sensor where do you get your boost vacuum point from cause my standard map sensor is on the manifold and i need to leave it on to stop a vacuum leak obviously.The gm one is a vaccum tube fitting.can you use anywhere after the throttle plate to get this reading i.e fpr vacuum pipe just tee into this? hope this makes sense! thanks

 

a few of my friends use 3bar map's and they usually T into the BOV vacuum hose.
