I'm diggin my '13 6.2L. Got one of the first Lariats off the line last Dec.
I would like to get in touch with 5 star and see what a performance tune would do to it, but I've just turned 10K miles, so I'd like to make sure all is really good, before I void the warranty.

Folks can say what they want, but the 6.2 & a 4.30 gear is just right for my tow/haul/carry needs.

Rock on
