Marketing hype and snake oil basically.
Don't you think that if Chrysler could rate the Hemi at another 5 horsepower by doing a legal tweak that they would be all over it in a heartbeat?
The Chrysler-installed software for your truck may have been updated since it was built and having the latest and greatest software downloaded into your engine/transmission control modules most likely makes for a better driving truck overall.
The reprogramming flash updates would address driveability/shift quality enhancements, false fault code sets, etc.
There are minor interior module updates for things like the courtesy lamps timing out too fast, etc.
