Cold air intakes also can provide better fuel mileage
DiabloSport/Bully Dog/SuperChips programmers and tuners
Members use these to gain performance, also almost all tuners have a MPG setting that will optimize your vehicle for better Mileage
CAT-BACK PERFORMANCE EXHAUST SYSTEM BY MAGNAFLOW
You can free up your exhaust flow also to improve mileage, I have seen reports of 1-2 more MPG's with an aftermarket Exhaust
FoldUp and Roll up Bed Covers!
Bed covers will make your truck more aerodynamic and can add a couple additional miles per gallon depending on how you drive and diving conditions, better aerodynamics=better mileage
any 1 mod and you are probably not going to see alot of gains, however when you combine them you will see more power and better mileage, however sometimes you wont drive your truck the same (keep you foot in the pedal) and you will not notice any MPG gains because the driving habits, however if you have a light foot and do a couple of these simple bolt on upgrades you will with no doubt see some MPG gains.
