im almost certain that mopar doesnt offer a computer upgrade for the hemi, and if it does, id be interested in reading about it...

as for the cold air intake and whatnot, i worked for dodge, and they dont make many of their performance parts for newer models. im certain that someone else makes their CAIs, as i know that borla makes a great deal of their performance exhaust.

the K&N kit for the charger and 300 seems to be the highest performing of the CAIs that ive seen...
