So Bill, about this..
Did you wrap the flex tube or is that a GM product?
I was thinking you are insulating that and the first half will help to keep temps down if... your going to keep it hooked up. (Idon't know if your required to use that EGR in your area) The point being you have a few options.
1. block off the hole in the exhaust manifold and route the tube into your airbox, this will allow you to suck cool air from your air box and keep clean cool air in your intake and the bonus is you won't set any codes while using a fully functional EGR system.
2. Set the EGR enable temp to 250*F in the PCM, this will keep that bugger shut and basically the same results are yours.
3. Remove it completely and turn off the codes, That'* what I did.
Every time I DEQ my car I install the EGR bracket and valve for show & tell but the flipping thing doesn't even have tubes going to or from anything..
Anyway... Nice work Mr. Looks great, you rock..
Oh yeah, one more thing, how is it your hands are so clean?
