You'd be surprised at how many semi trucks get tuned before they are even bought. You choose what you want them set at and they do it at the dealer. The same motor can have 350 hp or 500 hp and they keep all warranties. The fleet managers also have speed limiters put on them. They will pull like a beast until you hit that speed. there are still alot of trucks out there that are down on power but if you pay attention to a lot of trucks that are governed at 62 to 68 when they hit a hill they hold that speed.;)
