I'm glad your 6.0 is doing good, mine is going back to the dealer Monday again. Got a F350 4x4 auto w/ the 6.0, unfortunately I didn't do enough research and didn't have a computer when I went to get it :( Mine has a born on date around Nov. 02, before most prob's were fixed.At first had very rough hot idle prob's, trans shifting in and out of tow gear and dead pedal once in a while. Got reprogrammed engine and trans computer, better but still have rough idle (not as bad) dead pedal sometimes and the mileage SUCKS! 13 mpg, city/long distance driving.
When driving it runs sweet though , fast and lots of power, hopefully the newer reprogram will correct this stuff, cause besides the problems I love it.
