Harris Performance (www.tbichips.com) can tune your truck for no EGR.
this isn't only a good forum to hang out it's the best. If I were you I would just put on a new EGR so you won't see your check engine light on and GM techs know what there doing. When my EGR was bad I had high NOX to where it wouldn't pass Texas emmisiions. 
I hope you stick around. We do a lot of clowning around here, and the majority of us know our trucks.
