Well after doing some logging on 1st, 2nd, and 3rd gear pulls I'm starting to see that leaning out the safc isn't the answer but only hiding the problem... At the top of each gear here is what I saw::
1st 2 knock counts 0.88V O2
2nd 18 knock counts 0.78V O2
3rd 38 knock counts 0.74V O2
I had no misfires like before, however on the top end towards redline I'm getting really lean by having the afc leaned out so far. My conclusion is that there's too much fuel in the mid to high range and leaning the afc fixes this until 6000+ rpms when the o2 voltage drops and knock rises. When I tried to richen this area back up on the afc, then the misfire came back.
