This thread is HUGE, been trying to plow through it. Trying to figure out what is the best tune for me to use, looking for suggestions.
I have 07 unlimited Auto with 4.10 gears and 33" tires (more like 32's now). Most of my driving is under 7 miles to work. My initial impression is marginal improvements using the 87 tune the shift points still seem too high on the highway, I can hear the motor start to "bog" before it will shift. Thnking of trying the tow tune or upgrading to the higher octain fuel and try the 93 tune (we have fuel octianes of 87,89, 93 here).
Also, planning a long beach trip (8hrs), what is the best fuel/tune combo to maximize mileage and hold speed at 70mph?

Verify your speedometer is corrected as even small amounts of tire size differential can radically change shift points. Using a GPS to get where you need to be is a good way to go.
As for gas mileage I prefer using the higher octane tunes. In the summer months and with inflated fuel pricing it pays for itself. Additionally, the tow tune is going to further increase your rpm for shifts so it doesn't seem like a good avenue to pursue for what you are trying to accomplish.

I'm wondering with my 6spd how this will be affected with the towing tune. I am usually buzzing around under 2500rpm anyway. May have to try it on my next tankfull.

2/1000th? You can set the pressure to whatever you want or shut off the TPMS completely. Anyway the TPMS was just an afterthought to me with the tuner. I bought the tuner so the speedometer would be correct with the new tire size and maybe eventual gear changes. Since I got it the difference in performance makes it well worth the purchase price.
