I am personally hoping that forced induction will be on sale. I am leaning toward a procharger system, but that depends whats on sale. I don't think anyone could go wrong with any of the systems out there.
Procharger just ended there 500.00 rebate last month Edlebrock has 500 rebateit going on till the end of the year, We will have lots of great things on sale starting Monday of next week.
Unfortunately, I don't think they make one for the 2013 RT yet... just my luck...Hope your works out great for you though... Keep us posted on the outcome.
