Help With My Tune

To make a long story short, my professional tune wasn't, so I am attempting to do it myself. I am getting closer, I think, but I would like some direction. I have been trying to lock in my wot maf table since I was down at 9.0 afr and have gotten it closer to my target afr but now i have developed a KR issue at wot and also at part throttle. I would be interested in someone reviewing what I have and point me in the right direction to get rid of the KR and anything else that may need to be corrected. I am learning but this is my first tune. Thanks

What 42# inj are they? Brand?
