EGR Removal
#1. I have a 2001 5.3L and was wondering if the EGR can be removed completely? What I mean by completely is that if I were to buy a set headers I wouldn't need to get them with A.I.R. Is this possible or is my only option the EGR mod?
#2. Another question, is there any proven hp gains from doing this mod?
#3. If I do this mod to my truck will I need LS1Edit to delete it from the pcm or will my truck run fine right after?

EGR and A.I.R are two entirely different things. If you remove your EGR valve, you're going to get a check engine light. EGR is on the passenger side header and the A.I.R is on the driver side.

It can all be removed if you have edit or have someone remove it via programming. Mechanically, all you have to do is remove the hardware and block off the remaining ports. Although I am not from texas and we do not have emissions testing here. You may not pass visual with out them.

Can all that be removed or does that have to stay there? Can A.I.R. be removed or modified in any way to help in performance?
A.I.R. pumps some clean air into the exhaust system in an attempt to burn off any unused fuel prior to reaching the cats. It also increases the efficiency of the cats by bringing them up to operating temp more quickly. With the exception of the small parasitic losses associated with running the pump, I do not think this one affects performance much at all.
