So what's this knock issue happening, why?
I can confidently say that this tune is WELL within the limits of a stock setup running 91 or 93 octane fuel. Any jumps in knock control are likely due to poor fuel quality or questionable driving habits.

Something that i noticed is that the knock ctrl sits at .88 and with the ktuner basemaps i used to sit at .54
Mine has consistently sat at .49. 93 oct, no other mods, map slot 3. Even on Ktuner starter maps, I was at .49. It may just be your fuel. Drop a gallon of E85 in if you can.

I do have 2 gallons of gas left. so it must be the poor fuel.

Well, fill it up and see what happens. If it’s still not quite there, add a single gallon of E85 (to a mostly full tank) and see where it goes. I lived in IL (STL Metro East) for 5-6 years and the gas is meh all around the state.

did you pull the codes if there was any?

Also it's never a good idea to go for top speed runs...
