I wasn't thinking straight about the torque reduction map. I had it in my head that it was part of the shifting strategy, when it was really just a map for how much power was "taken away" during a shift. I think I will have to agree with your way of looking at it Cody, if less power is being sent through the tranny while shifting, the less wear/stress there should be(at least I think that's what you meant). I would like to hear why you two disagree with each other on this.
Why not go beyond stock and increase the reduction even more for a heavy tow program?
(on edit, that exactly what it looks like you did)
I would assume the issue would be with keeping the turbo "lit" under heavy load and with such a great reduction it might be easy to get under the turbo, but the tranny would be pretty happy, but I am just assuming and we all know what that makes out of you and me.
Think I am going to have to start from scratch on this one.
Thanks Cody
