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!

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
