I'm going to try to reflash it tonight and see if it helps at all.
The problem is showing up mostly in 1rst-2nd gear, not so much RPM related. If I had to pick an RPM I would say it happens anywhere under 3k. Its when I'm trying to roll through my neighborhood at 15-25mph, or stuck in bumper to bumper traffic where you are just kind of rolling along at a slow speed while trying to hold a steady light throttle. There is just no "light" throttle. Its either ON or OFF. Maybe I should take a video from the drivers seat. If I'm coasting at say 20mph in 2nd gear, then as light as I can apply the throttle.......the front end jumps up and it throws your head back. Its fine while holding constant pressure on the pedal. Then as light as possible reomove your foot from the pedal and it feels like it just snaps the throttle back closed and makes the front end dive and throws your head forward.
Its fine when pulling away from a stop, up shifting, down shifting, and great on the highway or while traveling in 4th-6th. Its just those low speeds in the lower gears that are frustrating.

I have been having the exact same problem. I actually just posted on Superchips forum trying to get help there with this same problem.
I will update you if I learn anything if you wouldn't mind doing the same

I can't say mine is that bad, but I have realized this same symptom. If you are at slow speed, like rolling through a parking lot. I lightly push the pedal and nothing, nothing, then it kicks in.

Was going threw the superchips website, and click on the update tuner button, and it started downloading an *.exe file. Does this mean you can only upgrade from a Windows PC? What if you have a Mac?

If the jeep does not know what size tire it has, than the esp thinks the wheels are spinning faster or slower than what they really are triggering the esp. either way, the speedo is WAY off even though i have it set to the proper tire size. what is the point of changing the tire size if it doesn't fix the speedo, what is the purpose of the function then?
