So I just got mine...and I'm not impressed! Background:
32" tires on 3.73's Automatic
Going topless/Doorless to Jeep Run today
One of the primary reasons I got this was to help my JK from searchin for gears. I had a Procal on it at first which helped GREATLY. I moved the JK back to stock and installed the 87 performance tune, calibrated the tires and did not touch anything else. I don't notice a friggan difference! The whole way to my Jeep run today it was searching for gears and primarily staying in 3rd while doing between 70-75. I haven't felt a difference between the Procal and this...I'm confused
I know that regearing is the only way to get it back to close to stock but I can't afford it right now so please do not mention that. Maybe I just set my expectations too high.

Anyway, if I was at the race track I would classify today as a pretty bad air day made worse by the winds.
If you have a GPS, select your tire size using it. A lot of people have had some erroneous tire size numbers even when using the recommended SC way to measure them. Besides that, it could be some PCM catching up, but I have always noticed an immediate improvement when going from stock.

Your right about this. I have fairly new 35x12.50/17 KM2's. I had to go to 33.25 inches on the Tuner to get the correct reading compared to the GPS. It is now dead on.

There are optimized shift points and firmness. I don't know how transmission line pressure plays into this as it's electronic and controlled by the PCM. The three items I am aware of that play into shift points are the throttle position sensor, manifold pressure sensor and speedometer. Beyond that I don't know as I'm a 6 speed guy and really haven't had much of a reason to dig for more information.
