what are the best mods for milage. i know driving smart is a key but there must be something that can be upgraded to help this. all and any imput is wanted :ford:
I'm surprised at what you said about the IDI. My Crew Cab dually 92' got between 16-18 city hiway w/4.10 gears and 7400lbs. The best my stroke has done was 16 hiway. And now that it's running right and I can't stop running to 80 at every stop it's more like 12 :doh:we have two trucks, a 1988 idi, which has no hope of great milage. the other is a f250 7.3l, 2wd, it has a lame bully dog chip in it, but my dad did that before i could stop him. thanks for the start
3.08's.... how does that tow? i have 3.73's and sometimes i wish to have 4.10's. ha ha.On the 7.3 Powerstroke:
Do all the maintenance stuff (air up tires to sidewall max, get a good alignment, check for dragging disc brakes,203 degree stat)
Don't sweat the chip. They don't much matter.
Don't sweat fluids. They don't matter.
Lose the automatic and get a manual.
Get 3.55:1 gears if you don't already have them. 3.08s are no longer available.
Get a tonneau cover. Better yet, a sloped bed cover.
The 4x2 can be lowered 3" in front and 6" in the rear.
Learn to enjoy coasting up to stop signs.
You should MPG close (within 3-4 MPG) to mine.
