I believe the 5.7 makes so much power, that out of the hole the 4WD guys will be much quicker because they can launch in 4WD w/o any of Toyota's "Star Safety System" kicking in.
It would however, be interesting to see a 2WD run down the 1/4 mile on slicks if someone can figure out how to fully turn off VSC & TRAC.
If you launch in SQ 2nd your truck will start in first gear then when it decides to it will shift to second gear (just like Drive) the only difference is that it won't shift to third.D-1st or SQ 1st ?
Bumping the limiter in D 1st pretty blows your launch,so SQ 2nd is proveing to be a better option.
Launching under 1500 rpm ? over 1500 ?
Better launch bite under 30 psi ?
Low 14's are pretty easy if you work at it abit.
Not sure about the 2WD models but for the 4WD trucks when the truck is at a complete stop push and hold the VSC button for 4 seconds. The "VSC off" light should come on. At this point you are set to go.........and go it does...
