I am looking for the same setup. I want to add a coolant filter and get rid of the EGR (or at least block it off). Can anyone tell me if there is a place close to Oklahoma that does this work, specifically OKC? Also, what is the advantage/disadvantage to removing the EGR or putting in a blocker plate (and where can i get a blocker plate if no diff)? Is the coolant filter still necessary to install if the EGR is gone or blocked? Also what kind of dollar figure are you all talking about to remove an EGR and install a "bulletproof EGR" or complete delete? Finally I am a pretty mechanically inclined person, but how hard is the EGR delete process for the average person with average tools and little time??? Thanks to all.
