I was wondering where did you guys hook up your vaccum line for the boost gauge? I am reading 0 boost! I tried 2 different places and its both the same. When I turn on the car it vac. to 20psi and and I drive it vacs to 0 boost. Can anyone tell me whats wrong?

i think you have it hooked up right. sounds like you have a leak somewhere. check all the vaccum lines.

does it stay to zero boost on full throttle?

normally when you turn the engine on it goes down to 20 vac. then when its running it should stay on zero boost, then on open or full throttle it should say show much boost you are running.

I think something is hooked up wrong.

I will put up a pic later on the day. Yes it goes to 20vac but when I WOT it goes to 0 boost. When I do normal driving it goes to 10vac or so. It never passes 0.

Are you sure you have power to the gauges when the KEY is turned to the ON position..?

I just bought a boost gauge also, which vacuum line do you tee? Is it the one that goes to the supercharger? or a differant one?

First take off the plastic cover, if your looking at the car head on at the top left of the intake manifold right infront of the valve cover there is a vaccum line. That is the one I used for my boost gauge. I would post a pick but I cant figure out how

When I turn the car on it goes to 20vac but then when Im driving normally it goes to 10vac and when I let off the gas it goes back to 20vac. When I WOT it goes to 0 but it doesnt pass 0. Is there a certian place Im suppose to hook the line to?
