You have to to make ajustments to a cam gear thats covered up... so run car test cam angle ... take cover off make adjustment... repeat process untill desired results is obtained 
Cam angles dont matter when you idle at 1100rpm and AT BEST, you're at -14psi, and at worst -7.9psi.....this is why we have cam angles![]()
why are you idling so high? I have a 72mm throttlebody and i'm idling at 900 rpms... MY vacuum at idle honestly isn't bad either. Less vacuum than stock cams but still completely fine.Cam angles dont matter when you idle at 1100rpm and AT BEST, you're at -14psi, and at worst -7.9psi.....
I do have to mention I have a 72mm throttlebody, so I'm sure I lost a slight amount of pressure due to volume added.
