On the Beech Bend run it was 13.82. On the 2.02 run, that was done at about 40 degrees, and it went 13.72 at 98.6. That was the quickest and fastest my truck has ever been. In fact, I'm not aware of any completely bone stock hemi truck ever going quicker, though at least one stock r/t went a bit faster a couple of years ago, and almost as quick.
My experience with tow/haul has been that it does absolutely nothing for dragstrip times.
