I agree that the valve doesn't need to be set to .96-.98. I do believe you will have better throttle response if you are closer to .96, my car seems to. I do not respect that you think I am lying to you about where I got these procedures, I doubt your going to have much of a claim of liability on a modified car (original ones probably still idle fine) that is almost 20 years old by now. These directions came directly from Ford Racing, I called them on the phone and they emailed the document to me, either way if you follow the instructions and there are no other problems with your car (vacuum leaks, etc) it works.
