How do i get my truck to suck less fuel? It's pretty much a stock 1/2 ton 99 Ram 4X4 with 33's .... but i can hardly get 10mpg out of it without it even being loaded. What are the quickest and easiest ways of bettering my gas mileage?

 

I have an intake, exhaust, fastman TB, highflow cat, a chip and bed cover running on 33's and all I can get is 12MPG. Your best bet for fast results would be the fastman. Although I noticed a performace gain I didn't notice much on the MPG side. But, I know that other guys here have.

 

5.9L 4x4 running 33's and you're shocked at poor gas mileage?
