4X, how much do you think these 10 speeds help with the Diesel engines compared to their previous 6 speeds? Lets say the Ford with todays HP/TQ with 6 speed would it do as well as the 10 speed or???

I would like to see a Dyno test showing hp to the rear tires while showing speeds from 15mph to 75mph with the two transmissions. I expect that the 10 speed would have much smaller dips at shift points and therefore higher average hp to the ground. But I hate to assume anything.
