EGR removal on a 01 silverado

I was wondering if anybody knows what I would have to do if I removed my EGR system from truck?

Yup, once turned off you can remove the harness all the way back to the PCM and plug the intake.

Is there a big gain or pick up with taken the EGR off the motor?

Small gain, if any. It is mainly used to block off hot exhaust gasses from re-entering the intake manifold to raise IATs...

I did not notice any difference when I removed mine.
I recently put it back on for my vehicle inspection. When I had it retuned, we did not even have to change timing.
