DPF Delete?
 

can anybody explain to me what exactly a dpf delete does? and what are the pro's and con's of it? thanks

+Milage +Airflow +Sound -Warranty -DPF related problems -Your friendship with the EPA
:c:

yeah it does that^. but a DPF works by just catching soot and leftover fuel but it restricts air flow and raises yur egt's and engine temp cause not as much air is moving through.in the 2009 may issue of dieselpower there is an 6.4L powerstroke with an ATS performace DPF. i cant find anything on their website but i would try calling a dealer and see whats up with it.

it decreases fuel milage by dumping raw fuel into the dpf. So that it can burn off all the bad stuff! (pollutants) imo they are a waste!

so much fuel that on the duramaxes it wont go into regen if the truck has a 1/4 tank or less

thanks guys. but what are the dpf problems? could you explain? im trying to figure out because i heard it helps with power and mpg's

A DPF works in conjunction with the oxidation catalyst and EGR valve to remove a majority of the NOx, particulate matter (think black soot), and unburned hydrocarbons. Soot is a natural byproduct from the combustion of diesel fuel. Inside the DPF is some kind of honeycomb structure that catches the soot as it goes through. After the soot builds up over time, the onboard computer controls fuel injection to allow unburned fuel to enter the filter at measured intervals where it flares off and generates increased temperatures that burn up the accumulated soot. All it is really does is eliminate emmisions for the enviorment and bog down the engine if you do remove it i think your bound to see improvemnts in power and mileage, might be illegal in california or something though. Hoped i helped good luck:c:

well i live in logan ohio :rocking: but thanks nick. do you have a dpf delete yourself?

but try askin on the forums for your year the guys will be more knowlegeable and be able to help you more maybe.

I deleted the dpf on my 08 powersroke it was cramping my style:argh:

:U:

Hey Dirty:

Do it if you don't have any visual inspectiosn or a pain in the butt dealer. Most of our LMM customers come to us getting 13-16 MPG and they have been able to get back up to 18-20 MPG +.....

Most states have a law against removing factory exhaust if it increases noise. Federal law (which local law enforcement can't enforce) mandates you can NOT remove the DPF. Unless you live in an inspection state, you probably won't have to worry about it.

I have a 2008 f250 6.4l.when I do the egr and dpf delete should I expect the check engine light to come on or heavy smoke coming out the exhaust.If so how should I go about it

Only if you were in the throttle really hard.

What about the check engine light

Why would you have a check engine light? You do realize you have to program the truck before you pull the stuff off right?

I do now I haven't done it yet just trying to get all my ducks in a row before I do.

These DPF's have an internal and pre DPF pressure sensors that determine when a "re-gen" is needed ...
the newer trucks that are running the DEF( Diesel Exhaust Fluid ) are reporting much better fuel econemy and power ... it pushes a blen of urea ( like 65 % urea and 35% water ) to keep the DPF and catilist clean and flowin gmore of the time and =not tossing Fuel at the catilist to burn off the waste and soot from poor tuning can cause ...

I have several busses, trucks and such all running different tunes from what the factory has them set at ... a tuner will help if you would not like to pull the DPF unit ... :tu:
