I have to give my car the "anti-idle surge vacuum leak" and it reads 14 inches at idle, and 16 inches with the leak plugged, surging away. 
I have a mild E-303, ported TFS heads, Holley intake and a 70 mm throttle body.

I was only getting 10 -11 inches when I had the e-cam and surging problems. Needless to say, the cam is gone, along with the problem.
