Bear with me, this isn't as adamant as it may sound.

As to case-by-case basis the two I mentioned seem to be the ONLY ones, that, together produce changes in overall average annual fuel economy (working from a solid baseline and stock truck). The magic boxes only "may" produce an increase, typically in only one mode of driving: stop n'go. The timing advances make it easier to not hang shifts (manual) and make life a bit easier for autos. The "evidence" for steady-state fuel economy increases -- highway -- pretty well doesn't exist. (This understanding is taken from the main guy at the best known aftermarket Dodge tuner; all my wording, however.)

You may be the person to allay the concerns: solid mechanical baselined truck, highly extensive records, and the education to pull off a set of proper tests (given the exigencies of private life and budgets) once the parameters are clear to you. Hope you'll give us Dodge guys another piece of ammo to chronograph!.
