Badger,

I have the Edge Juice with the Attitude module. It has a lot of tuning parameters. The Allison can stand over 900 ft lbs shifting from 1-2, 2-3, and 3-4. The 4-5 shift can only take 680 ft lbs. With 245s, my box generates 380 HP at 2500 rpm and 810 ft lbs at 2300. It is rated as a 125 HP/350 ft lb increase. I set my box to always defuel the 4-5 shift, and the box always defuels if the tranny starts to slip. Of course, I don't do any fully stalled 4x4 launches, because that would break stuff. I did some when I only had the 90 HP box, but the 125 HP box makes 100 ft lbs more torque.
