i have no tune at the moment on my zetec and no egr. is the dpfe going to cause any troubles for me? ive seen the hack where you block off one of the tubes but with no egr is this something to worry of?
EGR and the DPFE should be eliminated as one. One only works if both are in place. Just make a block off for the intake portion and toss the rest. Yes it will throw a code, but it won't alter performance.
i have no tune and no egr as well BUT, my CEL hasnt turned on since i disabled it about 6months ago. EGR/DPFE - info/fix i highly recommend reading all of this article but especially the "work around #2". that is what i did to my egr/dpfe.
