Is "tip in" meaning right when I start getting into the throttle?

to your second point, I believe that is the KR I am currently experiencing. I can stay in WOT and not see KR, but around 4800rpm, it starts to set in and increases to 3-4* before I shift around 5500rpm.

Maybe I should get more flow mods??? I still think that 17* on E85 with the mods I have shouldn't see any.. but I have worked this tune multiple times and feel like it is safe...
