haha want to know the specific numbers with a DPF vs without......simple answer ~300rwhp with DPF and so far ~500RWHP without. For those that think they can run much of a tune and retain the DPF....they have another thing coming. DPF will fail at a tremdous rate when ran with a significent tune. FACT!
Define significant tune, and the source of your FACT please. At what horsepower, torque, air/fuel ratio do DPFs fail at a tremendous rate?
Thanks Matt. I would be interested in your product and would personally love to delete the DPF. Appreciate the straight answer as well. Please let me/us know when it's ready!
Do you have any idea, estimate, how much of a restriction the dpf is?
If you are wanting to know on a stock tune how much the difference was just taking the DPF off, probably nothing. Just a minimal gain in fuel mileage since you can pull out the post injection fuel injection cycle.
On Edit, I don't know if killing the DPF is possible, but smokey tunes will make it want to regenerate all the time. Which may kill it .... one would need to know how many cycles a DPF is good for.
I would think just a proper tune (not a smoky one) with a dpf delete would pick up quite a bit of power. I'm also interested to see how much power is picked up by getting rid of the egr.
That is extremely impressive for a completely stock engine to be tuned to that level. I've never driven the 6.4L...but I heard some lackluster reports about the engine's performance. It goes without saying that if someone was to run this tune regularly or even often that other modifications will be needed, but simply being able to produce that amount of power with a completely stock engine is amazing!

Any tune that creates more soot then stock calibration will reduce the longevity of the DPF. As mentioned below you will be going into active regen considerably more due to the increase in soot build up. DPFs have a life cycle and the life cycle for the 6.4L was based upon stock calibration. Considering the warranty on the 6.4L exhaust is 100K typically life cycle is 50% more then the warranty cycle. Every OE's design requirements are different. Where did the facts come from? I design DPF's DOC's and converters for a living so I have a bit of knowledge when it comes to the effects of calibration. DPF life is directly proportional to the calibration used on the drivetrain. Considering ford is having a lot of DPF warranty claims in the stock tuning....aftermarket tuning will increase the DPF failure exponentially. Matt (spartan tech) can Vouch for this we talk quite frequently. I am all for what Matt is doing I think its great. If Matt or anyone else didnt figure out how to remove the regen cycles you can kiss doing any serious modding to the 6.4L goodbye.
I see your point. You are saying that pretty much any tune that increases HP and TQ requires a greater fuel volume and then would increase soot. More soot obviously would create more regens. More regens would mean a shorter life cycle for the DPF. Makes sense so a DPF delete with a tune that curbs the regen cycle is the way to go.
I am not a fan of the DPF in that it probably restricts MPG and Power, but I am pretty glad my new truck doesn't smoke like my old one. Guess there is no happy medium.

you got it bro. These trucks without the DPF and a mild tune do not smoke that bad at all. Here is my 'old' 6.0L with just and SCT Looney tune. I consider this minor smoke
Here is a bit more from my buddy rob
I just got back from a 1000 mile highway trip with my 2008 6.4 F-350 3.73 gears 4X4 crew cab with 6000 miles and driving 78 mph with the cruise on I got 14.7 mpg and this is figured long hand. This is a big improvement over stock form. I have a 150 hp Spartan diesel flash, removed the DPF and catalytic converter and has stock air box. It has alot better performance and fuel economy. All with very little smoke and it sounds real good, not too loud or annoying. It's the way to go.
Most if not all threads I have read from peeps that had put a tune on, stated they were getting better mpg even with the dpf on. If you are getting better mpg you are burning less fuel. Less fuel burned should mean less soot in the dpf.

Once you get an intake on there you will probly be up over 15... and its not even broke in yet! I think my 00 will be turning into an 09 in the near future...

Simply stated a tuner will yeild better fuel milage if you dont change your driving habits and drive conservative. If you have a heavy foot your milage will go down hill.
