Sounds great. But maybe I am a little confused on what is what. Are the air pump and EGR part of the same system? Or are they two different things? If I removed anything, it would be what is on the manifold and that pipe and I guess the little vacuum lines that run to it. Do I then need to remove a separate air pump? If I do this, I want to get rid of as much crap as possible. Thanks
