With 3.92 gears and those tires, probably down near 25 or so. Throw some
chalk dust and drive over it. Lower the air pressure until you get full
tread contact with the ground, then go a few psi lower on the right, five
sounds good.
Don't run in 4x4 mode. Good way to bust the xfer case chain, u-joint,
whatever the weakest link is. Never use 4x4 on hard surface when
transferring full torque.
First to second is a torque shift, after that it's HP that gets you to the
finish line. Put in some dyno time, get the numbers, figure out your
optimum shift points, get a shift kit and customize the shift patterns.
Or just mash the gas and hang on and be happy waist deep in the 16's.
