I am only pulling about 9 on my vac gauge at idle, and thought I had a vac leak. Since then, I have not found a leak anywhere and am starting to think I don't even have a leak. I have completely rebuilt for a turbo, but am still N/A. I have Crower 2's and am at 8.8:1 compression, the cam gears are both set at 0. Could the overlap on the cams be giving me a low vac at idle? I was going to mess with the timing a little, like +2 on the intake just to see if it helps and then go from there. What do you all think? Could this be what my problem is? I can't mess with the idle right at the moment because I have all of my interior ripped out with a bunch of electronics, I'm just brain storming right now to figure my low vac problem and shitty idle. It does idle very nicley until it warms up though, I am stumped. I looked everywhere and have found no leak. Help me out. I'm leaning towards the cam timing and overlap. TIA.

Like my taillights? Get used to looking at them.

Timing isnt dead on.
