And, yes I've fooled around with the WUR. I just didn't trust my wideband sensor, yet. Now that I've dyno-d and seen that they both matched, I feel more comfortable tweeking up the boost-cp.

Actually, I just got back from a little spin in the car and got to thinking that my most recent adjustment to the WUR I lowered the regular CP a bit thus richening my non-boost AFR's.

I believe this 'lower cp' has caused my AFR's to drop considerably as I accellerate. I see it on the graph and have really noticed it on my gauge. I think I'll bump that back up to the mid 14's before boost. It's hovering around 13.9 before boost right now...
