DPF delete?

Good morning guys. I'm new to the forum & new to the diesel scene as well. Just purchased a '13 F250 Platinum edition & I love it so far. I keep coming across he term DPF delete & I have no idea of what that is. Does anyone mind explaining it to me? What are the pros & cons to this? Also, what are the benefits of having your vehicle tuned? Thanks in advance & I apologize for my ignorance.

DPF= Diesel Particulate Filter...AKA Big Ole Cigarette Filter in your Exhaust. Look under the Passenger side...You Can't miss it.

The DPF captures all the Soot/Black Smoke. Once the DPF starts to get clogged, it goes through a process injecting DEF Fluid into the exhaust system and does a High Temp cleaning you could say of the exhaust system. There are plenty of videos that explain the whole process along with the pros and cons...biggest Con...Voided warranty.

DEF is not injected for regens. Diesel fuel is what burns off soot in the DPF during regens.

DEF is part of the selective catalyst system. It works in conjunction with the EGR to reduce NOx. DEF is only injected when the computer tells it.

You got it. And I am assuming you have seen your lie-o-meter drop down to 10mpg during the regen?

I haven't seen it drop to that degree. I'm actually averaged around 16-17 mpg so far. I have a tad over 1100 miles so far.
I've read somewhere that a delete on the newer 6.7s isn't as beneficial as it is on the 6.4s. Is this true? Also, I still haven't been able to find out what the pros are for the delete.

More power, better miles per gallon, sounds like a diesel, less oil dilution, and smells like a diesel. (You have to get a tuner to delete)

for about 15 minutes after the message pops up cleaning exhaust filter, your instantaneous mile per gallon readout should be like 10 to 12.

I haven't noticed that yet. I'll be sure to look closer next time.

Ok. More power and mpg gains are always good.

I agree with everything except your biggest con. Voiding the warranty is a biggy....but violating state and federal smog laws is much bigger. Looks like the EPA upped the ante in terms of fines...looks like in excess of $30,000 for tampering or removing emissions control parts.

Just saying the troubles with the EPA would probably be bigger and more expensive than the factory warranty issue. Something that needs to be considered in this day and age.

I definitely don't need that kind of headache. I've heard that H&S is a great tuner to use even with the emissions parts on.
