A few 6.4l owners have removed their DPF. You need a tuner and a piece of pipe to replace the DPF. Only thing is your warrenty will be done for by removing the DPF and a tuner may pose a problem too. Not to mention removing the DPF is illegal. Black smoke and the absense of a huge garbage can size thing from under the truck is a dead giveaway.
You guys have hit on a big part of the decision to go with the gasser. Too much unknown with the new pollution crap on the new smokers. At this point I know at least 2 dealers that will look the other way while the DPF got reinstalled in their parking lot for warranty work.
Fanatic, I have thought about gears. Seems like I would have to go to 4.88 to see a noticeable difference over the 4.30. That seems pretty steep for the 70% of my miles that are solo. At the present time with foot to the floor it shifts into OD at 109 mph according to the Scan gauge which at 70-80 mph agrees with GPS speed.
And if so, what size are they? (I want to check something out)
If you do go diesel, good luck with it and it's still a Ford

'74 F250 Highboy FE390 deceased! I've been wrong before, I'll be wrong again. Just wait and see.
I've been reading, tell me more..........
Price for it to "fall off"? Problems?
For all the big three?
DPF delete kits are available for all 3. On mine, I did a complete turbo back 4 1/2 MBRP stainless steel system, with the cool duals tail pipes with chrome tips etc..... It removed the DPF, and the DOC (diesel verison of a cat)
It does require a programmer. I went with the PPE programmer. I currently run it on level 2 (out of 5) which is a +90hp tune. It is not an ugly black smokey tune that you see some diesel guys running. Still very clean.
Mileage increase was approx. 3mpg average better.
Cost IIFC $1150-1200 for the exhaust system, $600ish for the programmer, and about 3 hours labor for install. All said and done, it was right around 2grand.
Problems = "0"
And before a bunch of you go getting your panties in a knot about warranty and the law etc.... This was all done through my local GM dealer, which is also a PPE dealer, and the law.........well lets just say I'm above the law! I do not live in an area that does any kind of annual inspections or anything. So for now I'm not worried about it. Some dealers are mod friendly are some are not. I guess I'm just lucky to be on good terms with my dealer and service manager.
And before a bunch of you go getting your panties in a knot about warranty and the law etc....
Talking like that, while owning a Chevy, will certainly get SOMEONES panties in a knot
If you had major engine failure, I'm sure someone from GM would come along and say "Hey, what's with all the mods" ?
Until that time, be happy and arrogant about your warranty status

The point I'm trying to get across here, is that warranty is not automatically voided because of certain things. In my case, am I pushing the mod bug too far to claim warranty? Maybe on a major engnie failure I am. But I have had a couple small things fixed under warranty already with no problems at all. Even my service manager has told me, if I break down far from home, to always be honest with which ever dealer I'm at. It may help them diagnose and repair a problem. If I should come across one of these hard-a$$ service managers somewhere, to call him and let him deal with the guy. That's good enough in my book.
I personally have been a mod bug for years on all my vehicles, and probably always will be. If I should grenade a motor, you won't see me changing my exhaust back so I can try to claim warranty anyway. I'm like to play, and don't expect GM or Ford or anyone else to fix something I cause. However, if my AC, for example, should quit, and some dealer says "oh, an exhaust system....no warranty for you" then you bet there will be something said.
There just seems to be a lot of misinformation on many automotive forums with one guy warning the other, not to do something because "all your warranty" will be void. This is just simply not the case. I even know of one guy that had is truck red-flagged by one dealer, took it to another dealer which reversed some modifications, then certified the truck to be 100% tip top shape, then had is warranty reinstated.
Tires are stock 275/70r 18. They are taller than what has been stock in the past.
At 33.1" tall, that's putting you at an effective gearing of 4.12 compared to the other trucks with the stock 31.8 inch tires.
Around 4.3% or so difference.
You could probably use a 4.56 or so ratio (10.6% more torque to the ground) and it would be a lot better.
Also, (shameless plug) you might want to check with Mike at 5-star to see what he can do with an 87 octane custom towing tune if you haven't already .

Oh and I do still own 2 other Fords..........
The warrenty on the truck itself won't be voided but the powertrain warrenty probably will be. Parts on the trucks engine that have nothing to do with the tuner, exhaust and etc would more than likely be covered also. I was refering to the powertrain warrenty, its my bad for not specifiying that.
Its good to hear you say you would not try to screw the manufacturer with the warrenty but the problem is lots of people will. I wouldn't know where to find a good dealer in my area. There are lots of them around but for the most part they all suck. Tuners and mods on the diesels have really cost the big 3 some money in warrenty work on past vehicles because of many dishonest people.
I am not an advocate of DPFs and all this emmisions crap on any vehicle. I only forsee the emmission laws getting more and more strict and at one point the DPF and other emissions laws just might be enforced.

Here in Metro NY, if your diesel puts out ANY smoke at idle, they will fail it for the inspection. Not sure what they are doing for the stock-DPF-equipped ones, but I suspect if they are checking for smoke at idle, they are going to check the DPF to see if it's there, and if not already, it's coming soon.
Warranty-wise, well, there's just no arguing that with some people with deep pockets

State and area have a lot to do with it. If I took the cat off my truck I would fail inspection.(visual)
I still think you can partly thank idiots like this for the EPA and CARB requiring DPFs on new diesels.
Visible smoke is a no-no. For Heavy-Duty vehicles (over 14,000lbs) "Teams consisting of a sworn police officer and an emissions inspection technician patrol the highways in marked vehicles. They are able to pull over any diesel vehicle, conduct a roadside test and inspection and issue a citation if appropriate. Currently, two teams operate in Clark County and one in Washoe County."
Also applies to vehicles traveling from other states.
From page 6: "b. Light Duty Diesel Vehicle Opacity Requirements. Light duty diesel vehicle exhaust
opacity will be measured under load on a dynamometer with an opacity meter and recording
device specified in Utah Diesel I/M Program Equipment and Test Specification (Appendix 5).
An opacity cutpoint for light duty diesel vehicles will be established at a value sufficient to
achieve a failure rate sufficient to ensure a 10% diesel particulate reduction. Specifications for
the test, the opacity meter, the recording device, the dynamometer,"
From page 8:
"10. Enforcement. The ExecutiveSecretary will encourage aggressive enforcement of
Section 41-6-147 by law enforcement agencies. Pursuant to Section 41-6-147(Appendix 1.b),
motor vehicles are required to comply with emissions requirements. The Utah Highway Patrol
and other law enforcement agencies are authorized to cite drivers of vehicles emitting excess
diesel smoke."
--
The list goes on and on.
Would I remove a DPF? HELL NO.

Not to mention with the recession.... cops, municipalities, local, state and federal goverments are looking for any ways to pick up more money. I am seeing cops set up speed traps in my area I 've never seen them set up speed traps before. The last 5 years surprise medium and heavy duty truck inspections have been increasing a lot. The police have been pulling over trucks and doing inspections (Portable scales, underhood, the whole 9 yards), mainly concentrating on the west bound rigs from out of Phiadelphia and NJ. I havn't seen them doing it to LD trucks yet, but probably will in the future.
Tires are stock 275/70r 18. They are taller than what has been stock in the past.
This is the problem, you have the same final gear ratio that I would have running 3.95 gears when comparing your tire to my 215/85/16 ( 30.4"). You would have to have 4.56 gears to have the same final ratio that I have with 4.30 gears. Gassers need low final gearing to be a good puller, Ford has a problem with setting up their trucks for smokers and the gas motor is get the shot end. If I was going to buy a new V10 right now I would have to make a deal that the truck will have 4.56 before I picked it up or no deal. Basically you have the same problem the guys that had 3.73 gears in my years of trucks before the 17" and 18" wheels.

I feel the same way as Mmax to an extent. There are days pulling a smaller (16-18ft) enclosed trailer or something I think should be no probelm at all that seems like I struggle a bit and have to have my foot way in it continuously.Yet, the next weekend I can hook my 11k lb fifther and 4k lb boat up to it and It does pretty well considering I'm over my rated towing capacity by quite a bit. I wonder if some of it isn't the adaptive learning computer (the 03s take about 20 miles), some of it weather related between wind, humidity, and temp, and some of it just the difference in trailers. I know with my fifther by itself I'm very pleased and have no problem running 65mph (speed rating of the camper tires) and if you dare it actually pulls better when I get closer to 75mph. Considering my 3.73s and 285 tires I relize why this is but overall I'm happy with about 80% of my towing miles. The other 20% seems to fall on hot, humid, windy days or when I'm just plainly asking more than I should out of my truck.
On a side note, I did some work on a buddies PSD last year with the exhaust and a chip and while talking with the dealer, whom was from colorado(popular over at the stinky site), I mentioned that I was after mileage more than power. I told him we lived in the flats of ND and the only thing we had to deal with is a bit of wind, and didn't have any mountains. He reponse was: "I towed my Toyhauler through ND earlier this year into a typical ND wind and it was a tougher pull than any mountian pass I've ever pulled. At least in the mountains you reach the top at some point!" It kinda of put things into perspective for me.
I really have no help for Mmax other than what I chauk my inconsitant towing behaivor too. Good luck but it sounds like your's seems to be a jeckle and Hyde type of truck and you may never find out what actually causes this, maybe just the nature of the beast, maybe there really is something wrong. either way, it'll be hard to diagnose.
