they may possibly put the money in to a motor like that and run the 2.5 class yes.....but tell me how your going to do with a protruded 2.5 charger and no weight on the front end to get it hooked? Ever see any of these 2.6 trucks try it with no weight out front? It's quite the scene. Getting the truck hooked up along with a protruded 2.5 charger will take care of your big money motor problem all in its own. So if they have to spend 25K to get the needed power to run a 2.5 class then i'd say they've got bigger problems....I'm not a Ppump guy and wont claim to know the ins and outs, but i watch a truck with the ag gov and one w/o and its a very noticeable difference, and what a pump would add other than power is beyond me, but hey once again im not a ppump guy so i could be wrong.
