i agree with hemiguy 100% toss the econ tune... these heavy a$$ trucks have to work so much harder to get moving with that tune that they actually suck more fuel, also check tire pressures, clean the throttle body, run some lucas injector cleaner through a tank of gas, buy or make a cai that gets rid of the "hemi hat", get a freer flowing exhaust, put in an e-fan, synthetic oil.... well, thats just a start but soon you wont give a sh*t about mpg's, you will be in a modding frenzy. lol

 

Yeah I should really clean my TB I can only imagine what it looks like
Plugs also made a bit of a difference for me but in the end I just do not give
a ***** about mileage. Truck runs fine and gets me and my gear where I need
to go thats all I ask of her.

 

Motorcycle gets my vote, but don't sell the truck! Just spread the love. My hog gets the summer miles, the Ram plays in winter. Big picture it's like driving a Honda only a heck of a lot more fun.

 

Thanks a lot guys im gonna be cleaning the TB and try running it on stock for a few hundred miles and see what I get. What plugs do you guys recommend using?

 

Regular old Champion Coppers. The Hemi seems to like them best and many actually report worse performance with the newer platinum ones (which cost a whole lot more).

With 16 plugs, and recommended 30k intervals, at least that's one plus!!!
