Fuel economy options what is best??
Hi guys, well my truck is a 2003 5.7 HEMI 2WD S/B I have a fresh service on ALL fluids, replaced spark plugs with Champion Platinum, Volant CAI, Gibson exhaust. The truck is "supposed" to have a Superchips program but I have yet to verify this. I have done all of this, and still the truck continues to get 8-9mpg city and 15-16hwy, two tanks of fuel later my total average is 11.5mpg based on math NOT on the onboard computer.
Any ideas? I love my truck, but it's eating me out of house and home with fuel costs.

when I got my 03 ram in 04 it too had Gibson exhaust and volant intake. I averaged low numbers just like you until I swapped out the Gibson for a flowmaster with 3 inch exit just before the right rear wheel. the overhead said before I was getting 9.8ish and after the fm and gutted volant box a bit the over head said 11.1 and that's all with same driving habits.

I used the Flex-a-Lite 180 Extreme (since replaced with the 183 Extreme), complete kit, nothing extra to buy. Good documentation too. Not a difficult install at all, hardest part is getting the stock, clutch fan off.
Many have done the Taurus "pick 'n pull" fan as well, with good results... I believe there is a DIY in the FAQ section for this one...
