Having owned my 2012 for two years now, I never really paid any mind to this advancetrac/traction control thing until reading this thread a couple days ago.

So I decided to turn it off for grins, and I must say I love the way the truck responds with it off. I will never leave it on again. It really drives a whole lot snappier without it.

I always hated what I would describe as a lag or loss-of-power or hesitation when up-shifting from 1-to-2, and now the shifts are a whole lot crisper with constant power through all the upshifts.

I'm sold, advancetrac OFF.
