I know buy a ricer if you want gas mileage. BUT, I'm all stock (k&n) and maggy exhaust) around town i get about 12 mpg babying it and about 9 mpg pulling my 20ft bas boat. I'm not worried about the mileage as much as I am whats causing it. I done the following:
1. NGK ITR6
2. Replaced O2 Sensors
3. New high flow cats
4. All new coil packs.
Ford says its running fine but it still seems like it takes too much throttle to pull the boat and drive around town. Intercoller has never been cleaned, 57k miles, couild that be it?
Thanks
Dave

300-320 a tank after e-fan install. (was 260-280)

 

homemade or a kit ?



Back on topic:

300-320 is around 15 MPG
I have never checked the mileage on the L.......

 

I dont know too much about this, but i bet that difference was caused by the amount of hwy. vs. city driving done. I dont think an E-fan is gonna get u roughly 1mpg better gas. I could be wrong... just my 2 cents.

 

the best mpg i have ever pulled doing 60mph on a 60degree day nothing but highway miles with a dyno tune on street tune was 13.9mpg. thats it I average 10.5-11.5 all the time.

 

being very good I can only manage about 15.5 to 16.5 once and I am VERY GOOD cruise the whole time at 70 to 72 no boost except once.

I'm getting 260-280 a tank too, and I'm installing e-fans next weekend. Hope my mileage goes up too!

 

Bone stock with oversized tires all hwy I got 17mpg.. ofcourse she needs some TLC so probably could have done better.

 

I put the LFP E-Fan kit +pump on the truck last September. Prior to it I had the other mods (3lb, SCT 9100, Magnaflow Muffler, FTVB) installed for a year always seeing 260-280 miles when the Low Fuel light comes on.

After the E-fan the Low Fuel light comes on now and the trip shows 300-320 which is what my truck use to be when it was in stock form.

I have not done a dyno since the E-Fan +pump but at the track I went from 12.68 @ 108.14 to a 12.46 @ 109.17

 

I don't check it. It's too depressing.

 

same here. it seems no matter how i drive i need to filll up every 3 days, 4 at best.
