BEST fuel mileage out of the 1997 7.5L engine.

Hello I am wondering what is the best fuel mileage anyone has got out of the 460. How did you achieve it and how much money.
Thanks Logan

what about any computer chips for the 460. Has anyone tried them

Has anyone tried using super chips or anything in that sort of field to acquire better fuel economy? I also found a site they claim their exhaust system will gain 10 to 15% better fuel economy with 68 more hp and 100 or so torque. Could this be true?
Thanks Logan

zxwut is right.

I am looking at buying a 1997 460 crew 4x4 right now, and I was floating some ideas about improving mileage as well. The best I can think of are: Full performance exhaust system, performance ignition, a moderate rear gear, and a light foot.

Truck in sig w/ 3.55 gears: I've managed 14.2 and 14.5 both on 250 mile trips, on a state highway with practically no stops and a constant 55-60 mph. Truck was unloaded and I was following other traffic; not drafting really (don't want rock chips in the hood), but I wasn't the splitting 100% of the air myself either.

imho,you asked the wrong question.
you should have asked who has the BEST AVERAGE MPG,if you wanted to see real world numbers that mean anything.
also asking for the amount of tanks back to back were included in each persons results could help you find how accurate each were,and which to toss to the side.
just a suggestion for next time.

My 460 seems to get better milage loaded on the highway. My work site is approximately 25 miles from home and it drinks a half a tank a day. But, a short while ago I went to another town about 20 miles further down the road to pick up a free slide in camper I found on CraigsList and round trip it only used a quarter tank. ?? AnD it was extremly windy (cross winds) the day I picked up the camper. What gives?
