May I ask why you guys are using an allison instead of something that doesnt defuel? Also why not use a lighter 9" rear?

My Allison doesn't defuel at WOT, just around town at part throttle. Shifts smoothly for DD, but puts the power down at the strip.

I didn't disable the defuel, it just stopped defueling at WOT after it was built. But I'm only at 660 HP. Do they defuel again when running a zillion HP?
