My stock boost gauge is plugged into the boost port under injector 6, and is not reading anything. Maybe the vac line is broke, but i remember trying my aftermarket gauge on that same boost port and it wasnt reading anything either. Would there be a problem with that boost source? Im just trying to figure out if I have a vacuum leak-boost leak.Tonight, Im gonna plug my aftermarket gauge on the fuel pressure regulator line and see if I have vacuum. Ill let you know what happens. Thanks again

I have the gauge tapped into the purple-pink one on the diagram on the plenum side and my boost controller is plugged into that same line but on the turbo side of the motor. That line is not the one below the throttle body.

Well the aftermarket one is tapped into the vacuum underneath the FPR, that goes from the throttle chamber, under the tb cover and to the canister. The purple one on the diagram. And, my factory gauge is plugged in behind the balance tube. The car runs like a dream, boost fine and idle great.

Hey guys, Have a little newb question here, I started my car yesterday and noticed I didnt have any vacuum when idling, it shows just above 0 on my boost gauge(aftermarket), but when i rev it it goes down. Would this be a vacuum leak? would this be related to the CAS, cause I advanced the timing a little bit to trouble shoot the sputtering. My factory gauge is plug in behind the balance tube, but doesnt read a thing, might be broken. And my greddy is tapped in the vacuum underneath the FPR, that goes from the throttle chamber, under the tb cover and to the canister. The purple one on this diagram: I also plugged my greddy behind the balance tube before and it wasnt reading a thing, would there be something wrong with a boost source going to the balance tube. Any help would be appreciated. R32 GT-R Thanks
