When working properly, you should see no difference in performance with the EGR in place.

A properly operating EGR valve allows you to run the timing further advanced without pinging. Advanced timing provides better performance and fuel economy. GM vehicles didn't react as badly as some Ford models to inoperative EGR's. Some of the Fords of the mid to late 70's rattled so bad with a plugged EGR they were scary to hear.
Hmm cleaner engine bay, cleaner air we breath? Tough choice.

if you have the opening in the intake then keep the EGR its a good thing. no reason to take it out. it doesnt hurt any performance as long as its working.
