When I did mine I talked to allen on a phone call. He was very helpfull and pleasant to deal with. He suggested since I have the 4L80e that all torque management could be removed. With his suggestion I had it removed.

I dont drive the truck real hard, dont take it to the drag strip (other than to be a spectator) so I feel very comfortable with all tq mng gone.

call allen, he will lead you in the right direction. BTW, I have several hand guns and would suggest to save your money and buy both
