I dropped out of school early so this may be incorrect mat, but if you are getting 8 and you go to 10 that's a 2 MPG increase. So since 2 is 1/4 of 8 I think that's a 25% increase. I think that's significant, what more would you want? Lets make it easy: Drive 20,000 miles at 10 MPG that's 2000 gallons of fuel, drive 20,000 miles at 8 MPG that's 2500 gallons. 500 gallons at 4 bucks a pop is 2000 green ones. I don't know about you but around my house that buys a lot of kimchee.

Hm so if i am gettin 12mpg right now once i install the programmer and delete kit I could expect a gain of at least 25% which should be 3 mpg gain. I was expecting more because a buddy of mine had told me he gained about 7 mpg city driving , guess u can't believe everything u hear.

Leave you stock air filter. My uncle has had two engine go over his aftermarket air filter on a 6.4 and he brags up how he gets 2 better mpg over it. I have a 2003 F450 with the 6.0 and I get 9.5-10 and I wouldn't care if I could get 14 with a air filter kit. Fuel is cheaper than a engine.
Use stock air filter.
Aftermarket is junk.
I had a K&N that failed, then a AFE system where the boot cracked wide open at the turbo inlet, allowing anything to enter the turbo directly.

people that say they're getting 17 mpg city, or 26 mpg highway, are telling you what it says on the dash, which is not correct.

Yep, what he said. I drove to Miami and back to fort myers last week. All but about 5 miles on each end was pure interstate. Truck computer got to 21.2 MPG. I filled up and did the math and it was 14.8. Which was what I expected from a DRW truck with a 4.30 rear axle. I would say if a tuner gets you a 25% increase it will pay for itself in no time.

Also guys, the 1st 6.4 ECM software that came out, and the last update ( I can't remember what they're #'s are or if there was 2 or 3 updates), are different driving and mileage characteristics too.
Despite reading the only difference was error or failure detection, the later calibration at the very least uses more relaxed spooling.
If you don't believe me, load up the 2 on the same truck, driving the early calibration runs a whole lotta boost ( and egr i assume), while the later calibration seems to relax the induction a lot, which I think would net better mileage.

after reading these post's this one has me concerned the most as I am almost sure my latest pcm flash was 1123b and it was done 3-4 years ago! if so it could be a flash that increases boost? and any idea if running the Banks tuner would over ride this setting? We took a trip [900miles] empty and my hand calc MPG was 17 mostly hwy .last week I towed from LA to mid.AZ and it was looking like 11mpgs [rough estimate] when i had a loose wire on the no.2 cyl and ran poor the whole way home so could not really gauge the mpg's .I have a 25ft toyhauler 6500-7000 lbs and this trip I drove out there on the 3 setting NO tow haul mode and was ok with the shifting [not 100% I should have stayed in the pedal longer on a few grades] thinking of running 1600 miles to arkansas but would like to know a ballpark figure on towing mpg's .I have 3.73 rear end w/4x4 and wondered if anybody has seen 12-13 towing with this setup?................PS.when I left AZ. I was not auriferous in any shape or form and the damn roads beat the **** out of my truck!
The early ford program seems to run a lot more boost, when mine got flashed, it ran a lot less boost. I assume that helped mileage.
I believe the tuning guys based the tunes they released based of ford original programming, but it's hard to tell, and my opinion.
13 MPG towing anything sounds reasonable, but it all depends what, obviously, and driving habits etc.

Banks has updated their tunes a couple of times but not with the 11B23 in mind.
I really can't relate as I am so heavy that I will tow in stock most of the time.
If I am running lite I will leave it in two but that is all I do.
In my planning I budget for 7 mpgs. I always seem to do better though.
I am working on a 5K trip this summer from MD to AZ through NM and back.

I don't know. I've been towing with diesel pickups for 13 years now and I would be very supprised if you got a real 13 MPG. I couldn't get that with a 7.3L/373RA towing my Cardinal 5er which weighed maybe 11,000. Problem with the trailer is not just the weight but also pulling the front of that trailer through the air. There is a lot of resistance to overcome. if you don't believe it wait until you get a long run against a strong head wind. But, if you can get it with the 6.4L it will be driving with RPM below 2000 and boost under 20 lbs for most of the drive. Good luck and let us know what you get.
Thats the truth, I have an old heavy pull behind, and it isn't any higher if much than the truck.
Heavy as hell, but doesn't burn much fuel at all.
And when I say doesn't burn much, I mean I've seen bigger fluctuations of fuel use with the empty truck.

well I'm just gonna keep asking this question till I hear what I want To!.....seriously some one posted about percentage gains earlier and I need to be grateful that the truck /trailer combo is showing10+ mpg when my class"c" lazy daze was getting 7mpg with a 70 mile an hour tailwind! but while vacationing with the motorhome in 2010 we met a guy w/ a6.4 and he told of some mpg's in the high teens and I foolishly believed it ,so like a lost treasure I search for the elusive 12 mpg figure to show up on my calculator and who knows maybe it will someday with a good tailwind..........or a towrope! thanks for your reply's! always grateful for other's experience as I hope to keep her for quite a few more years
