There are a lot of variables in 0-60 second times in a diesel truck. Whether or not you use 4wd is the biggest. I have never tried it with the 250 or 275 tune. I found a calculator online once that used my 1/4 mile time slip to determine and it said 4.1 with the 310 tune. That was when my truck was pretty basic (other than the SunCoast).
I would say between 5-7 seconds with the 250 tune and 275 tune in 4wd depending on how hard the truck is launched.
