Running 91 tune on superchips with 89 in the tank?
Can this cause me problems? We only have 87,89, and 93 here at the pumps. I have been running the 87 tune, but I always put 89 in the tank so I thought I'd change to the 91 tune. It seems to run better, but will it hurt my jeep to run it this way?
Is it to lean? I live at sea level and I have a CAI and Exhaust.

I run the 91 tune with 93 octane. I love the increase in power and mpg's over stock.
Realistically at the current prices the difference in a fill up of 87 and 93 is less than 5.00. For me its worth it. Just my thoughts.

For those of you running the 91 tune, what kind of mpg's did you gain over the 87?
Agreed on the actual cost not being THAT much more in the end so I'm thinking of trying 91 on the next fill-up and changing the tune to go with it.
I'm guessing it would take a couple tanks worth to notice any real difference though while the computer re-adusts itself?

Same here. I definitely noticed a difference between the 87 tune and the 91, and so now run it (the 91) all the time now. Works even better with the SprintBooster!
