Hey jayman84 where did you get your chrome rain guards from?

 

I have a guarantied, fool proof, can't fail, cheap, easy to install part to get better gas mileage. Best part is its free! Go to your local golf course or if you indulge, your golf bag. Take a ball and stick it under the gas petal. Another way is to put a raw egg on the petal between your foot and the petal. Can get a bit messy though.
Only way I know of to get better mileage is to keep your foot out of it. But thats kinda hard with the Hemi...
