Definite Difference in 91 and 93 Octane Tunes

[Jhamil1]

Hello,

I run my '14 Charger 5.7 Hemi on 93 octane. I programmed in the 93 octane stock tune and noticed a difference on acceleration right away. The shift points increased and the engine wound out in each gear. I tried the 91 octane stock program to compare and noticed a difference to the shift points right away. They seemed to not wind out as much as the 93. I'm going to run the 91 for a week and then switch back to the 93 for a final comparison.

One question. I have a CAI and can't figure out how to program it into the tune. I don't see anything in the advanced tune area for it. Am I missing something? Any help would be appreciated. Thanks.

I am pretty sure I read that the 2011 and up don't lean out with cai, so there isn't a need for that option.
