im gonna run a million grounds this weekend and hope that fixes my hesitation =/

tap into those exact wiring harness points. Unfortunately I'm still not running right. Itested the 6PI and they moved when I blew in the line. I'm going to take a look at the o2 sensor tonight, Somethings got to explain the freaky AFR gauge readings.

ok its fixed, after all the problems this week it came down to a faulty boost sensor, I swapped in one from the donor cars and Voila! Thanks for all the help

How did you know it was a faulty boost pressure sensor? Did you test it, or did you just take a wild guess and replace it?
I was having similar problems, but I think they are ground realted. I have run some additional grounds, but I have not completely eliminated the 3800 stumble. The only ground I have yet to do is the boost sensor.
The car runs siginificantly better, but still a very slight bump at 3800 (especially with the headlights or A/C on.
I am wondering if I have a faulty boost sensor, but I don't have a spare to experiment with.
