 I recently purchased a 2008 f250 4wd with a 6.4 powerstroke. What a complete piece of #$@@#! Ford should be ashamed! I do realize that the engine in this pickup is manufactured by international harvester however Ford should not have placed it in one of their chassis. This boat anchor is so bad! I have had several fords and this will be my last! I have also had other manufacturers diesel pick ups over the years. First of all the thing gets 8 to 9 miles per gallon pulling a mere 6k pounds! Ha!The pickup gets only 13.6 empty on the highway. I previously owned a 2005 duramax that would have castrated this piece of crap and got 15.5 mpg loaded! This powertrain pkg is junk!
