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...
Same here. I've read studies that showed that K&N's are the highest performing system. Why else has the Big Three on certain models decided to use their equipment?
MrKrisSullivan, you sometimes have to be careful with some of these products that claim to make improvements. I've known people that have purchased chips before that found that they made absolutely no difference. My advice is talk to people that have Chargers, 300s, and Magnums to find out what they have done to their engines to get what output. The only thing you will have to remember is that some upgrades that might have worked on the LX's 5.7L may not turn out the same on the new 5.7L since the engine has been updated, though an exhaust and air intake system shouldn't have changed that terribly much.
