GM has eliminated EGR valves by going to variable cam timing. By going to variable cam timing the "power band" of an engine can be extended over a broader RPM range. EGR can be done more accurately with cam timing than introducing it through the intake where no 2 cylinders get the same amount. Removing a properly functioning EGR valve from an engine will not ever increase fuel economy or power. Most of the time it will have an adverse effect.
