I know this has been covered a thousand times but after reading 20+ threads on the matter noone seems to have the same situation as me. I bought a car recently and it came with a glow shift 30-0-30 gauge in it and when the car is off it reads 0. Once i crank the car it reads inbetween 18-22 vacuum. When i give the car a little gas it jumps up to around 10 vacuum. When i hit well into boost the gauge just reads about 0. I know it is not the gauge because i actually had a gauge that i know for a fact works sitting in my room that i swapped out and it does the exact same thing. I can take the gauges and blow on them with my mouth and they will read a few psi so it cant be the gauges. The gauge line is tapped into the intake/fpr line. One thing, i dont know wether it will make a difference or not but i just pulled the center console up and found a avcr unit thats working, could the way it is installed have any impact? And yes it did make my dad when i found the avcr because to my knowledge the car was stock .
