I am by no means savy when it comes to performance but not only are the speedo, gear ratio and tpms adjustments great but I gotta say that tow tune kicks ass. Im running 35s and use that tune with my stock 4:10s and have no desire to regear. My gas mileage has improved as well. An excelent piece of equipment. DO IT

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?

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.
