Mufflers and a K&N are by no means a big enough list of mods to require a remapping of A/F ratios, spark advancing, and so on.
I agree They are just minor mods that give a little more throttle response and sound. I Kenne Bell Super charger for the 5.9 would be a nice upgrade they make a nice one for the Crysler 4.7 Engines also.
