I have searched and have not seen any polls on tunes with Flashpaqs. If I missed it,flame away. For those those who have Superchips what tunes do you like/work best for your JK??

 

I've only tried the 87 tune with 87 octane gasoline, and the 91 tune with 91 octane gasoline. I didn't notice any difference in performance or fuel economy, so I stuck with 87.

 

91 tune and tow tune have about an equal amount of support. There is probably a third group that just runs the 87 tune because of perceived cost.

A minority of people use the 93 tune, and there hasn't been much success with the Mileage XS tune.

 

87 for mine. it works well since I dont want to pay the coin for higher test gas. And I worry about pinging with the higher octane.

Only gripe I have is that 1st gear can be touchy at low speeds.

 

91 tune on my 2-dr 6-speed. Felt better than the 87, but not until I had run a few tanks of gas through it first.

I also run a SprintBooster on mine as well. The combination of the two is fantastic.

 

91 tune. Noticed better low end torque on hill climbs on road.

 

91 tune and tow tune for my 10 6-speed with 33's. I got the most power and mpg's.

 

So with the 6-speed how much difference does it actualy make? is it worth the money?

 

4door Auto, 5.38's, 35's, Colorado altitudes.

87 tune/fuel - no real difference from the basic ProCal calibration
91 tune/fuel - worse performance than 87
Tow tune/91 fuel - best all around performance for me
Tow tune/87 fuel - tried this after reading other posts, worked about as well as tow/91. (don't know of any negatives, but stopped running 87 fuel 'just in case'.)

 

What does the sprint booster add to the performance with superchips? I run 35s. Based on what I'm reading, I guess I should step up to 91 octane and tow tune?
