If you are gonna pull some heavy loads the 6.4 rocks! Stud it, EGR delete and DPF/DOC delete and the truck is awesome.. it kills my 7.3 workwise..
that said.. I am running my 7.3 the past 2 weeks cuz the 6.4 is down w/ popped headgaskets..but a set of elite studs will fix that.

Neither is the 6.0, now the factory bolts can be a problem but that depends on how you use the truck. 508 HP and I am still using stock gaskets.
There are a lot of misconceptions on the 6.0, as I am sure there are for the 6.4. One of them has to do with emissions. I am running well above stock and just tuned HP/TQ levels and not only do I have working coolers, but I also have the original coolers that came with my truck.
You really have to do your homework with regard to the 6.0 and 6.4 engines. If you do that and follow what you find, then you'll be glad that you didn't go with the 7.3, it just doesn't compare to either one of those.

I would almost suggest that there be a mini course or orientation to go thru upon the purchase or consideration of an oil burner. Your driving habits as such need to change just enough that there is a difference.

If you pull heavy loads then you will stretch the studs. I am deleting my EGR system and studding the head b/c I would rather do it now while the head is off.
The power of this truck is amazing.. After I get it right we shall see about reliability. I think the DPF and EGR systems are the weak points of this engine..
Feel free to come to Bean's Dyno day dec. 4th.. I'm shooting for 600hp haha

Where I am coming from is more in stock form or within a 100hp.
Just running heavy in stock form is what it is made for and it won't blow the top off.

I'll be there, but I stopped using his dyno though. It doesn't like Fords all that much. I have always dyno'ed less on his then everywhere else.

I have a F-450 weighing in at 10k.. it's a total pig stock. I had to put a tune on it. If not for a more responsive truck then at least for the fuel economy gain of a chip.
I would think that almost anyone would want a tune on the 6.4's. The fuel economy is so poor that it's easier to justify the spartan or SCT.
Having a 6.4 makes you appreciate my 7.3 tho.. I ran around all week in my 7.3 and got 22mpg. I went 760 miles on a tank.

I don't miss my 7.3 one bit and besides that, I never got that good of mileage out of my trucks. I have always been lower then the "average" MPG quoted on forums. Mainly because I work my trucks. Not too often that they don't "see" a trailer.

Tuners are performance enhancers, not MPG gainers. Some may see gains, some may not, some may even lose MPG with tuners.

The 6.4 sees better fuel economy in higher hp tunes. I will see 11mpg in my 250hp tune and 9mpg in my 210 or 175 tunes.

However, MPGs aren't something that can really be controlled as there are way to many factors that go into them and changing one factor(ie tuner) isn't going to do much.
In order to really tell if you chip/tuner improved mileage, you also have to account for all the other possible variables(wind speed and direction, how fast you were going, ease into the pedal for both going and stopping, terrain that you traveled, distance that you travels, ambient temp, barometric pressure etc) and you have to keep as much of them as consistent as you can when you do your testing. Hell, even changing the oil can give you better MPGs then running on older oil. Switching diesel stations from a low turnover to high turnover(or vice versa) can also affect MPG as diesel doesn't like to sit.
Could the chip/tuner improved your mileage? Sure.
Can you show conclusively that it did so? No, not unless you have a lot of specialized equipment to do so.

I would worry more about spare parts when the time comes for fixing things. 6.0s ran from 2003.5 til 2009(E-Series vans account for its running til 09), while you have from what 07 to 10 for 6.4s, not a lot in terms of parts. I think International is still producing the 6.0s as well, maybe for the 6.4 that I don't know.
