Ran with a second EGR valve set up on top of the installed one for years. With an '03 it doesn't care until you run through the diagnostic tests then see a low EGR flow code. The concept behind letting the installed EGR valve be disconnected is reducing the EGR gas flow, hopefully keeping the EGR cooler, cooler, getting a little more mpg with a more violent fuel explosion, and giving the finger to the EPA. Having run it for more then 150k miles I'm not sure it does anything except the finger part, with the exception the valve stays cleaner.

Sounds like what I was aiming for when I started this thread - some real world experience running the dummy EGR setup. Seems like an easy substitute for an EGR delete.
As for giving the EPA the finger, I have to deal with them all the time in my work; nothing makes me happier than flying the fickle finger of fate their way whenever possible.
This thread really surprised me as I hadn't seen this topic discussed in a long time.
The reason I kept a valve in place rather then a plug was I heard if the turbo over boosted the valve would push open and relieve the excessive pressure. In case that was true I'd rather have the valve there.
