2010 FORD f-250 Diesel 6.4m 3,000 miles

I have installed the 80hp tune but have not seen any mpg gains. I have seenthe horsepower gain it seems, however, it shift really hard now.

At 60 mph 1X10 boost, 65 mph 1.5X10 , 70 2X10 boost

I have read thru some of the posts and it says I should have chanegd my tire size first, before installing the tune. However, I have no ability to do that.

the Stock the tires were 275X65X20 Goodyears, and
I now run 325X60X20 Nitto Dunes. So there is a good bit of difference. However, I really did not lose but about 1MPG when I switched to the Dunes.

Any advice on what I can do? Currently I am only getting 11-12 mpg city. When I tow it drops down to 8-9. I have not ran the towing tune yet, but plan on it. Highway I can get 14.5 stock, have not ran a trip yet with the Predator.

I love the truck, but it gets worse gas mileage than my H2 did.

I know we do not buy these vehicles for the gas mileage, but I just thought it would be better. I know a guy who has a 7.3 and gets 20MPG AD, and my buddies 05 Dodge Cummins Stock gets 15 city,18 hgjhway though he is only running 33's.

These dpf trucks will never get mileage like the older diesels, but we're always working to improve the current product when possible.

So the fact that you did not answer my question about how to change the tire size mean, you can not do it with the Predator on the 2010? It is like my predator is a predator light model. scaled way down. I am now second guessing as to whether I should have just spent the money and got the Spartan. I am not sure these limited tunes are worth the hard shiffting and no MPG gains. Thanks for any advice.

Have you tried adjusting the tire size?

I was not trying to avoid your question.......

I have no option for it. My predator is missing that. the only thing i can modify with my predator is the top end. I can not change revs, or anything else.

OK, there are new updates in the works that should allow us to fix that.

any idea when I can expect it ? I noticed when I downloaded the latest update it was put out the back in January, and the 2010 6.4's have been out about a year now. I am just trying to get a gauge of whether I should sale this, and go a different route, or wait for you guys to figure the 2010 out. It has been a year and it appears you guys are really struggling. Thanks

Ditto. Love my '10 F-250 6.4L but the mileage is the same as my '03 Chevy 2500HD with 6.0L GAS motor.
