Not to worry though I turned my 10' RCSB 4x4 with 3.55's into a 13 second beast with just intake, exhaust, tires and a tune.
Thanks for the info. It's impressive what these trucks can do. I can't wait until I can get a tuner for a 2012.
As a sidenote, I wonder how much drag the front differential and front driveshaft spinning all the time causes. Wish they came with manual hubs.
