Here's something I found on another board that I think explains the EGR and it's functions pretty well.
There is a port on the headers that directs some of the exhaust back into the intake via the EGR valve (exhaust gas recirculation). EGR is only used at part throttle operation and not at idle or WOT. It cools the combustion chamber by slowing the burn times and subsequently requires more timing to get the slow mixture to burn. It also increases fuel mileage slightly and reduces emissions. Removal of the EGR system may be against the law in your state and usually requires a retune to reduce timing in these areas to avoid knock. Generally EGR is good and there are no performance gains to be had with its removal. Some people remove it to clean up the engine bay
