also no chip or programmer and only 30000 miles milage should go up with more milage

Well walked away from the 2008 f250 I was going to buy, just read to many things about the mpg.Going to look for an older one with a 7.4 I think, or a GMC Durmax?

Did you buy it when the 07s came out? Very hard to find an 07 5.9 now. You can't beat the 5.9 for mileage and power, although the Dmax comes close, but I'll never have a V8 diesel. I love my 06 dually but the 2010 Laramie I drove was off the charts nicer than mine.

The 6.7 has more power and torque than the 5.9 but not the fuel mileage unless you delete the emissions stuff. Lots of aftermarket mods for it now too. It's still an inline Cummins, just a bigger bore and stroke...

I have an 08 F-350 6.4 30k miles, 10k of them pulling heavy Formulas. Absolutly zero problems. Mileage is around 12-13 empty,10-11 loaded. There will always be bad press on anything new. Dodge,GM,Ford all good trucks,but I wouldn't stray from my Fords.

Have you ever chipped out any of you trucks you've owned? This is my first diesel. That's why I'm a lil leary.

36K own mine and never a problem.

I have an '08 6.4 F450 and tow a 47 Fountain. It tows great. No problems whatsoever.

You don't need a power chip towing that. The nice thing about the 6.4 is the twin turbos which don't allow any lag. My single turbo doesn't hit till around 1300-1500rpms which really sucks. If I was pulling anything over 10k I would get twins.

I've had two diesels and have not chipped either one. You're not going to hurt your truck with a mileage tuner. It will pay for itself within at least six months and continue to save you money.

I have a 2008 F-450, 4 door, dulley with the 6.4 Twin turbo Diesel, I love the truck it has a Spartan tune, DPF delete, intercooler pipe, and a air intake, the truck runs great and gets 19 MPG, get a Ford, they did not take a bailout:grinser010:.

Thanks for the info. I will have to check it out. The boats not that heavy. Right at 10k loaded with trailer. Pulling my skid steer and dump trailer is a different story. That's just over 13k.
