friend of mine has one talked to him at eagle truck pull and he tried a bullydog and he said about 5min later all hall broke out. Said the dealer knew right away that he had played with it when they plugged it in. I guess it ended up takin out a couple of sensors. Other than that he like's it. he's had 03, 05, and now an 08 all ford's and all of them was played with.

I have an 08 6.4L F250 3.73s and get around 18 to 19. I have not towed anything heavy yet.

Welcome, Skeeter.

That's awesome! Is that hand calculated mileage?

well thats what the computer tells me. I will do it by hand on this tank to see how close it is.

Thanks for the welcome.

Yeah let us know. We're always looking for first hand knowledge on these new motors.

I took my 08 up to ft crack a few weeks ago
at one point the computer said 55L/100km
or 4.7 mpg
with a 40'gooseneck and 3000 kg
i went to a dealership to see if it had been reflashed while it was in for te radiator recall
no such thing
but i guess there is lots of talk about ford releasing a flash to improve MPG as it is the #1 complaint

4.7 mpg??!! Wow!!

I was told that there is in fact a flash for economy gains. I also had a dealership in Ontario call me the other day asking for items to improve mileage and I said to this guy that sure it can be done but I was not going to be responsible for the warranty issues as the programmer would most certainly void his warranty.

He said it won't it and I said give that to me in writing - he never called back.

You didn't actually think he would did you?

So I have to wonder about this reflash. I wonder if it gets you economy at the expense of power output. Have you heard anything on that aspect?

No, I haven't. It would seem that some dealerships know that it is available while others do not. I'm not sure - but I'm not the dealer...

I can get close to 23MPG if I can keep my foot out of it....

Yes, you can do it like julian if you take the dpf off and get a kem tuner to turn the regen off. Thats the trick. Hes one of the lucky guys that has it.
