At some point you either don't have enough engine to pull the truck along at the speed you desire, and or you don't have safe enough or large enough brakes to be going that fast in it any how.
In my mind that cutoff point is around 60 mph, and if you want to go faster start with better brakes,

i can attest to all of this. grigg is right on with his statements
. what i'll add to this is that at those speeds your looking to obtain, handleing becomes an issue also.
just yesterday i had issues with brakes and handling and i was only doing 50 in my 350 on a trip i was returning from.
some say you run these trucks as fast as you can all day long. i disagree because i have two of them that i drive regularly. for the safety and what the trucks like to run at the way they are is any where from 45-53 mph contstantly
