I love my truck, it is a 2004.5 5.9 Cummins, it runs like a fine timepeace, wish I got a little better mileage.

 

Get a smarty, boost fooler and call it a day! Depending on what tranny you have upgrades will be neccesary! Get some guages too! Play with the smarty #5 seems to be the best for milage on a stock truck POD at about 65. But you will have to experiment with it!

 

Scratch what's posted above, you neither need nor want either of those things if all you are looking for is a little MPG. Go out and buy you a Diablo Sport Predator (it's only $272.95 on XDP), put it on the 100HP Tune. Keep your foot out of it and watch the MPG's go up. You should probably get yourself a boost and pyro gauge you don't HAVE to, but I like to keep an eye on things. Genos has a slick two in one gauge from Westach that does both boost and pyro in one gauge, and then you can pick up an SRT10 single pod pillar and not lose your grab handle.

If extra mpg is all you really care about, go with the Diablo over the Smarty. I'm pretty loyal to Marco's products, hell I have one the first Smartys ever made and I love it. But, go the cheap route if you just want mpg gain and keep your foot out of it like Cumminstexas said!!!!
