Just bought a 2004 dodge quad cab four wheel drive with the hemi. Just wondering what should i expect in terms of mileage and some good pointers for better mileage. (exhaust, chip, k&n) ect.

And you are worried about fuel mileage?.... Be very, very worried.....But seriously, if there is any way to get better mileage from a 5.7 Hemi, I would like to know about it.

I averaged about 12.5 after I put a flowmaster and power programmer on it.

I have a 2003 with the 5.7 and get around 15-16 if I lay off the gas. I have a a new K&N intake and flowmaster exhuast. Thinking about gettting a programmer and seeing if I can't get any better mileage out of it. It is a single cab so that is probably why my numbers are a bit better.
