the egr is an Exhaust Gas Recirculation valve, it pumps exhaust into your engine to keep the airfuel mixture from burning too hot while cruising down the highway, exhaust into an engine hurts the hell out of performance btw...

Actually,
you are as wrong as it gets. Recirculating exhaust gas back into the combustion chamber cools the chamber (odd, I know, but it does) and leans the mixture, resulting in IMPROVED fuel mileage. WOT throttle performance and cruising are completely different beasts.
