    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.

    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...

    It went to limp mode or there was a code that caused the problem.
