Yeah, a friend of mind recently bought a 2010 F-250 diesel & he loves it. Took it in to the dealer for a software upgrade (factory) & said that it ran like a new truck. Also said that he was now getting 23 MPG on the highway (I'm sure he's getting that from the computer, so YMMV). He's tickled to death with it...
