did you look for any oil around the pulley system? One of my buddies had an annoying squealing from the belt/pulley and it was found that oil was getting on it.

I was wondering if anyone ever ran into this issue or know what might be the problem. So my problem is that in any gear, at any speed, at any RPM, if I go WOT the car would stumble immediately and the AFR would run pig rich at less than 10:1. Then about two seconds later, the power would come on and the AFR would start to climb back up to about 12:1 and feel like it should. This happens every time without fail. Now if I slowly bring the RPM up without going WOT and into boost then the car would not hesitate. So that leads me to believe that it is something to do with the supercharger and not a wiped cam or some other problem.
There are no CEL or any codes.
I was thinking that it might be the bypass valve but I figured that if it really was the BPV then wouldn't it affect boost the entire time? But the problem seems to correct itself if I stay on the throttle at WOT. I was thinking of disconnecting the bypass valve and running with it shut just to test it out. If the hesitation goes away, then I can nail it down to the BPV. Good idea?
What say you?
