EGR is something you want on a street vehicle. You need a working temperature controlled vacuum switch (and a good valve) since it hurts performance and driveability on a cold engine. The EGR valve cools the combustion chamber slightly (exhaust gas doesn't burn much) which reduces pinging. On a performance engine, this lets you run more ignition advance or higher compression. On an emissions turd like the 305 in my El Camino, it lets it accelerate up hills without sounding like a yard of gravel in a cement mixer. Another benefit of EGR is engine with it usually have an exhaust passage through the intake manifold which helps with cold driveability.
