Dak 05 v8 performance suggestions wanted

Greetings all, I'm new to the DML list - been lurking for a couple weeks, time
to ask a question of you.

I recently traded in my 98 Dak for an 05 (Mineral Grey SLT, quad cab, 4.7l v8,
5spd Auto) - yes, I know I'm in the minority, but I love the look of the 05's,
the body style and retro gauge look reminds me of the first vehicle I bought
back in '76 - a 72 Dodge short bed (360, 30-over 9.5:1 pistons, Offenhause dual
port intake, carter 650, purple shaft cam, 3600 stall converter, damn that
thing screamed). But I digress...

Anyway, I've been working on the improvements I want for my '05 - spray in
bedliner, tonnaue cover, side step rails, etc. The next area I want to focus
on is performance and/or gas mileage. While I'm pleased with the snap of the
4.7L, there's always room for improvement - right? Plus, even at best with the
day to day driving I do I'm only able to get around 15.5 mpg (17.5 if I have a
long freeway drive). Lots of start/stop on my daily drive, plus living in SE
Wisconsin, we're victims of having to use reformulated gas .. 10% ethanol.
Gotta love the reform gas.. lowers gas mileage (fact), ruins your fuel
injectors (fact), increases gas prices - and basically does nothing to improve
the air quality. And don't get me started on the fact that Wisconsin has the
highest gas tax in the country. Bitter? Maybe, just a bit - but again, I
digress..

Anyway - looking for mods that will help performance and/or mpg, ones that are
reasonable in cost and won't void my factory warranty. Any suggestions you
might have would be greatly appreciated.
