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!

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.

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!

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.

Better MPG and Performance
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...
