Just picked up my 2012 300 with the 5.7 in it. I got it as a CPO, so I have a 100,000 mile powertrain warranty, which I'd like to keep. What can I do to maximize this motors potential and stay under warrant? And what type of power should I expect? I'm assuming the answer will be something along the lines of "get an intake, catback exhaust, and a tune".
