i have been running superchips in my jk for about 5 months. i started with the stock tune with my 35's. then changed to 87 tune. then tried tow tune. i am currently on the 91 tune. i ran each tune about a month to get the feel for the differences in power, fuel consumption and shifting. Long story short, the 91 tune is the best in my opinion. jeep runs smooth and shifts well. mileage is about the same as the other tunes (maybe 1/2 mpg less). i will be leaving it here from now on .

cheers

 

there are a ton of posts on this topic......but I am glad you took the time to try most of the settings on a real test, cause I just went to the 91 tune, and have left it there since...lol.

I am happy with the 91 tune.

 

Here in RI we have 87, 89, 93 Octane.

The 93 is about .30-.35 cents more per gallon.

So is the 91 Tune worth the extra costs in fuel for daily driving??
Thanks
