Anyone tune one of these yet? I guess 2011 and 2012 have different ecms than the older ones. I'm not familiar with the new gen v8s. I'm coming out of a lnf cobalt ss that I had tuned and always adjusted the tune my self after that. Any pointers on torque management and tranny setting adjustments this is a bone stock truck, I'm just looking for better driveability and better mpgs as a bonus
