0 - 60 Time
0 -60 is measured by Torque software running on a 10" Android tablet that is connected via Blue Tooth to a Blue Tooth adapter plugged into my OBD port. The 0 - 60 program senses the starting movement of the truck and then displays Elapsed Time in seconds as soon as the OBD says 60 mph.
As far as 2wd vs 4wd is concerned I can not successfully launch the truck in 2 wd. It is fairly lite in the rear end and all hell brakes loose if you try. Even in 4wd things can get a little sketchy depending on road surface conditions. I have made a few runs in Manual shift mode starting in 2nd gear. 1st is very short and you can get into Rev Limiting very easily so 2nd is a better starting point under some conditions.....
