I have a 2014 with 3.21. You'll find the final ratio of a 3.21 vs 3.92 truck is exactly 1 gear apart.
i.e. A 3.21 truck in 4th is nearly the same as 3.92 truck in 5th, etc.
Empty, they're traction limited off the line. The 3.21 is faster as you're shifting less. Both will spin 1st gear to redline with a good launch.
The 3.21 revs low enough in 8th that MSD will never kick in, the 3.92 revs higher (equal to 7th on the 3.21), but MSD will kick in more often. If you get 33+ tires, then get the 3.92. Otherwise I feel 3.21 is perfect.
