Noticed this thread on a search,I tune GM vehicles from 96 to newer somewhat regularly.
Alot of the performance tuning itself will actually increase MPG,it's the difference in the weight of the drivers foot and their habits that usually drop it.
I've yet to mess with it,but plan to start building some "eco-friendly" tunes that will easily have plenty of performance and plenty of mileage savings.
I will be using my wifes 2004 Impala 3.8 as a testbed,and plan to play with things like water/methanol and hydrogen generators along with tuning to achieve the best mileage possible.
We make weekly 6hr trips usually,so i've got plenty of drive time to test with.
I'll be saving and keeping a log more than likely-I'll post it up sometime. Working out some software issues right now,plan to be up and running next week though.
