Well, the blockoff plate is a really nice piece, and fit perfectly. Pros? A couple less vacuum lines under the hood, and no more EGR solenoid to look at. Cons? None, at least for my car. I got rid of the EGR since I have a ZZ4 cam and it has enough overlap to "self-EGR". In fact, GM got the ZZ4 crate motor smog-certified in Cali without the EGR valve so I know it should be fine, should I ever need to pass emissions again (thank you Collector Registration!). I just had to program out the EGR in my chip; if you remove the EGR and don't do anything in the program, I think it'll ping at light cruise where the EGR normally comes into play.
