Welcome to the forum, and a good start would be a good 4" exhaust and a tuner.
Let me know if i can help.

I am a sucker for tricks and toys...but does it make a difference in mpg? Power is easy, but I want to be able to drive it to work everyday....it breaks my heart to take the wife's Honda CRV.
How much does a tuner run? Recommendations?
As for the exhaust, I am worried about the install -- since I think that a bad install would eliminate any gains on flow....
yep a tuner and exhaust will help, then you have to control your right foot

Yes they will both help, i would consider a PPE,Quadzilla,Diablosport for the tuner and a 4" mbrp turbo-back exhaust. The PPE tuner is capable of the most power and is guaranteed atleast 2mpg better. The quadzilla is what i run and im very pleased with my results. If want some pricing let me know and ill shoot you a pm with some.

Welcome to the site, The thing about diesels is that the more power you give them the better the mileage gets. I get around 20 and can smoke most cars on the road.

Welcome aboard !!! Its nice to see you got a 2WD as they get much better mpg than the 4wd guys! As these guys have stated, you can get the parts you need to improve your mpg anywhere from 2-6 but, unless you want a new trans, dont add more than 90hp. Thats the limit of the stock Allison. I would also suggest getting a set of gauges if you add a programmer. EGT and Boost are the ones that need monitoring.
I can offer you a package deal on everything you need, or can do piece by piece.
