I ran the 87 tune for a while, but recently changed to tow tune. I like it much better!!

Do you guys feel more power with tow tune...?
How isw it better than 91..? or different?

Also , i have 33/12.5/17 so i just automatically put it to 33" my speedo is showing 5mph faster than it actually is... should i lower or up the size?

Go outside and measure your tires, like the info from superchips tells you to do. They are probably closer to 32" or a bit less.

I'm running 87 tune now. What differences do you see in the tow tune? MPGs similar?

Felt a difference in power and doesn't shift out of OD as much. I didn't notice a significant difference in mileage, but I'm not driving my Jeep everyday to work anymore. I never tried the 91 tune.
