I went with the 5.7\8-sp and plan to get 30+mpg after all my mode's (a guy can hope).
There are more Mod's for the Hemi than V-6, but there are some.
Tire pressure to MAX rated psi.
Change the T-stat to 180. Adjust Temps in ECM.
DIABLO Sport has a Tuner that contains a Eco Tune, may even be a Tuner guy that will build a specific tune for the V-6.
Lower does work, or at least extend the from dam 2+".
Just some idea's.
