4X4ord. 2 gear(2:1) in a Aisin and 4:10's out back is going to hold back a lot on the full exhaust brake setting. If the VGT exhaust brake makes 75HP of braking, then in 2 gear wouldn't that equal 600+ hp of braking at the rear wheels?

AT that weight, what speed would 600 hp hold.on that grade. You seem to be able to compute the numbers going up, so you should be able to computer them coming down. I know at 24,500 in 4th(1:1) and 3.42 out back, I had to step on the throttle once in a while on 6% grades to not slow down to much. Would that not be 225HP of braking at the rear wheels?

Torque is multiplied through gears not power.
