There's not a lot most of us can do about it... our company actively messes with the ECM settings (not just speed and HP) and our loads tend to put us over 70k on a regular basis. That and our minimum fuel economy requirment pretty much guarantee that we aren't going to be drag racing other trucks.
In a 60mph zone doing 62 in 1-lane construction one fine day, I get this: Driver: Hey Prime, can't you go any faster? Me: Sorry driver, my mom won't let me go over 62 Driver: ........ Unfortunatly that was the end of that conversation, guess he didnt like me anymore lol.
