DPF delete?

[Lungbuster]

Has anyone done one of these to their trucks? I am curious as to if the mileage does increase? I am not looking to get get a tuner and make it a "hot rod" truck, just would like to get better mileage.

I believe that with the DPF delete you will have to get some sort of tuner. It will program the truck's computer to not dump fuel or DPF fluid into the exhaust. Also you might have to do the EGR valve delete. Just because you buy a tuner you don't have to set it to the highest power setting, you can always leave it at stock settings.

What truck are you wanting to do this to? It will help others help you on this subject because each engine is different.

6.4 powerstroke. I know the kits disable the dpf and egr. Also have to do the exhaust and an intake i believe. which is fine because I was planning on doing that anyways

A lot of guys on cummins forums are saying they get 3 to 4 MPG increase. I have a '12 dodge with the new HO engine and it makes me sick every time I change my oil! it's black as night the day after changing it and it smells like fuel from the EGR. Word is look into EFI live also.

Oil in diesels is always black. Normal.
If you do the delete you have to have a programmer. You have to trick the truck into thinking all the emissions stuff is still there. It's expensive to do unless you have the means to do it yourself. You should also expect to have problems getting people to work on the truck once it's done. We are not even supposed to bring them in at all with these mods.

I get 19 mpg on the freeway in my 6.7 cummins with my h&s mini max.  I've got a 6" lift and 35's.  Stock with emissions I was getting 16mpgs hwy, 12 driving to work.

You will get better mpg's for sure but I think the biggest benefit is performance improvements. You'll spend $2500 to have a shop do the delete setup. Does it make sense to spend that money to save money on fuel?? If you have to worry about emissions test you may want to look into it a little further too.

Yup did mine myself along with an EGR delete. Made a HUGE difference in fuel mileage.

Well fuel milage will be nice. I am running 37's so the extra HP will be nice. I have just heard that if the DPF goes out it is like 5-6K to replace/fix. I have not researched that yet , so why not spend the 2k and just delete it. Plus with the tuner I can change for the bigger tires.  Plus I was told that if you change it to stock settings it will pass emissions.

[jackelope]

The DPF is covered under warranty for a long time.  100k miles. You won't pass emissions i dont think because you don't have any emissions on the truck. They test opacity with diesels. How much smoke or how thick the smoke is from tailpipe. I think what you're going to see is your truck is supposed to have no smoke from the tailpipe. When you do the delete it will blow smoke. Is just some smoke too much on a truck that is supposed to have none??  Don't know. DPF trucks are mostly too new in WA for emissions tests. It will be interesting to see what happens in the next few years.  We were told at school $30k fines if we work on them. I can tell you they stink like a diesel sitting at idle. There is no setting it back to stock so to speak. The programmer is there to make the truck think it still has all its emissions stuff. Put it back to stock and your check engine light comes on and the truck will prpbably run like crap.  Check engine light comes on, you fail. Not trying to talk you out of it. Just throwing a few things out there you need to consider.

My dad just deleted his 6.7 CTD. He doesn't care about the mileage,he was just tired of the never ending check engine lights.

If his is like all the other deleted 6.7s,he'll gain a few MPG.

Deleting his 6.7 was very easy. IIRC he is in to it less than $700.

Deleting my 2011 Dmax has never crossed my mind. Its getting better mileage than my '07 5.9 CTD with no emissions ever did.

[jackelope]

Did he do it himself, Rick??

[Rick]

Did he do it himself, Rick??

Yep,we did it in his garage.

We did what are called "California style" deletes for areas that require emissions. He can have all the components back on the truck in about an hour.

Cool. I was told by a customer that Dynomite charged around $2k to do it all with the box so your $700 DIY makes more sense.

A delete capable programmer is $5-9 hundred with a $150 pipe.  Unplug the sensors before and after the DPF and oil them and then bag em and tape em up.  Install the pipe and the tuner.  Instant HP and mileage gain.  If you need service or inspection, install the DPF and sensors, drive a few miles till the computer catches up.  Reprogram tuner to stock and take it in.  I'm not saying the factory will cover the warranty, but the emissions will be stock.  I've been researching this for a long time for my 08 duramax and I'm about ready to pull the trigger, but I'm in a non emission test county, and my warranty is up anyways.
