Done w/ DPF

Say I was to run an midpipe deleting the DPF......is there a way I can manually go in and disconnect the DPF until I get a tuner? I know it would throw a CEL but I don't care. As long as it won't regen. Put 2 K on an oil change and it already past the full mark.

Nope. Not that I know of. Gotta have a tuner for the DPF or EGR stuff.

Nope. Must have a tuner that supports DPF removal, otherwise the truck will shortly go into limp mode after you start it.

If you had a Dodge, yes, you could delete it.

if its dumping that much fuel into the engine you have something else going on. deleting the dpf won't fix that. ignoring the real problem will probably result in major carnage, and denied warranty because of mods.

i dont understand the DPF delete stuff. there have been several companies out there make awesome performance numbers with factory DPF and exhaust. these trucks are engineered to perform with the DPF. to each their own i suppose.

Diesel Power July 2012 issue - "deleting this and removing that is a shortcut to nowhere. we can make this Powerstroke run better, improve its fuel economy, and still get it to burn clean"

the article is titled "How the Emission Laws we curse every day make diesel Better".
Page 24.

What's your definition of "awesome performance numbers"?

The emissions stuff was very much an add on. The engines run much better without them. My truck runs great and nearly smoke free (always smoke free unless I punch it. And then I just get a puff that clears up when the turbos light...) I burn clean every day without the emissions...

Not saying that a truck with original equipment can't be made better, but I think it's best for the motor without the DPF... You can't honestly tell me that the heat and the added unburnt fuel during Regen is healthy...

I know turbos and the less back pressure the fast the spool. Not to mention I just did an oil change....didn't even wait to get to 5K and I drained almost 5 gal. from the truck. 15 quarts is about 4 1/2 gal. can u guess where the other 1/2 gal. came from? Diesel from all the stupid regen's from driving around town so much. I hit 9 regens in 2,800 miles. NOT COOL!

a properly functioning new Diesel will run great when properly tuned with the DPF attached. i work on Internationals (Maxxforce and DT line), i deal with DPF's every day. the temps are brief, the ECU injects extra fuel into the DPF, not the engine, to burn off what particulate has been caught (when the ECU detects too much backpressure), and its done. yes the temps are high, but they are in the DPF, which is designed to handle it. even Cummins is using DPF's now. the only issues are when the DPF wont regen because of a damaged DPF or a damaged injector. if your truck has DPF issues, i hope its still under warranty.


i want to mention that i am not trying to start a fight, im just voicing my experience. if you delete, thats fine, thats your choice. my truck had a cat only when i bought it, and i cut it out. i just wanted to point out that these engines are designed to run with the DPF intact (since the 6.4 is a Maxxforce 7), and by EPA and government regulations, we are in deep you know what if we remove these. we are talking thousands and thousands of fines for the truck shop, the tech that did it, the driver of the truck, and the owner of the truck.

if you are having to regen that often, you have a problem. i would have it checked ASAP. it either is not regening properly (injector at DPF issue, backpressure sensor issue, etc), or your DPF is damaged. now, if your truck is out of warranty, by all means, tear that sucker our and recycle it (its worth a lot of money). you DO NOT want to pay for one of these out of pocket. trust me.
