E4OD/351w mpg
What kind of mpg can I expect from a 91 f-250 with a slightly moded (headers, 2.5in. exhaust with flowtech warlock mufflers and a mild cam) 351w efi? Also, how are the E4OD gears set up, is it always in OD or does it shift into OD automatically?

E4OD is electronically controlled by the engine's computer. OD can be turned off with a separate button on the shifter handle. My 95 E150 van got a best of 16 mpg with it's roller 351, E4OD and 3.55 rear with 28" tires.

I don't know about mods, but my rig is tuned up, runs well (except for that pesky cutoff problem).
Stock 351w running 4.10's, 245's, in a F350 4x4, I can get near 14mpg on the highway at 65.
Around town I'm down at like 10mpg.
When my exhaust is in place, I'm saving for rims and tires, thinking about using a ratio calculator to get my gearing closer to 3.73.
I think I might sneak out a extra mile or three per gallon highway.
I dunno, it's probably all a wash anyhow.

I have a 95 F 350 4x4 with the 5.8, E4OD, 3.55's, and 265/75-16's. It has Ford shortie headers with stock exhaust, and a K&N FIPK. I don't get over 13 with it ever. I average about 10-12. I get about 10-11 around town and 12-13 on the highway. I am not easy on it, but not hard either. I have a friend that has an F 250 with the same engine, tires, and gears but with the ZF 5 speed and he says he gets 16-17 driving 25 miles one way back and forth to work. I don't know if the E4OD eats that much mileage or what, but that is quite a difference.
