For me it was because my 05 had the up pipe with the scoop welded into it restricting flow... and while I was putting in the unrestricted pipe I put in the metal disc to block off the EGR.
I couldn't really tell if the unrestricted pipe made a difference or not... I thought I noticed a smal improvement, but who knows.
I can't tell if the EGR block off did anything for me either. I've been lucky with my truck, never puked fluid... I just did it as a precaution while I was in there. Had the radiator flushed prior to my last trip pulling the Toy Hauler... they over filled it and still it didn't puke. Temps were mild though... 60-75 degrees. I'm probably jinxing myself. It'll probably puke commuting to work this week.
