One question where do you guys have your boost gauge tied into?





The one with the blue rice cover stuff going into the firewall opening goes to the boost gauge. I have it mounted in the change holder lol

Also for some reason my vac reading is way off but I feel less vac too when driving

Mine at 10.2 psi boost idles at 18vac

I went to 14.8 psi boost it idles at 8vac

I think my boost controller is leaking... I heard a leak but I think its the actual controller now..

I'm going to check all my T's too

Idk I have no idea lol any help is appreciated.

Most of us tap into the MAP sensor line which runs along the top of the rear valve cover. It is a hard plastic line.

did you try putting it back to 10lbs to see if the vac is still affected?like keep the BC hooked up still and turn it down to 10..

I did that and the vac went down to 20 at idle but once I boost it to 15 it goes to 10
