I cant speak for the specifics of whats involved in doing a delete on the 5.9L.

EGR stands for Exhaust Gas Recirculation. A portion of your exhaust (up to 20% depending on the engine) is put back into your engines intake to be burned again. This in turn reduces the amount of NOx coming out of the tailpipe and in turn reducing your emissions.
