Hello everyone, I found this site through "Fordmuscle". I am a Ford Man though and through, and have been for over 40 years. I have a 2006 F250 with a 6.0. I have had two other F250's with 6.0's and have liked them. My 04 was stock, my 03 had larger BF's and my new one is stock. Other than the tires on the 03, the trucks were stock, yet the 03 seemed to have the most "get up and go". My 06 does not seem to have the same power, as far a pick up goes. My Ford dealer has downloaded and installed all the updates and he says that the truck is operating in normal limits with no codes. Does anyone have any thoughts on why this one feels slower?
