I picked up a 05 F250 with the POS 6.0. Was a one owner truck with 80k miles and i got a good deal on it i think so went with it. I was wanting to know what websites you guys use to get info on the trucks. I have had people tell me that you can get a tune for better mpg and more TQ to pull with. Also not sure what mods are worth doing to help the truck and what are a waste.
