From what I've read there is no performance gain. You will lose a few mpg. Mainly it cleans up the engine bay.

The egr stands for exhaust gas regeneration it just cleans up the exhaust gasses leaving the engine

It recirculates the exhaust gases back into the intake manifold to reburn the inert gases for fuel mileage lol 👍

pros: the cars no longer eating it's own ****, cleans up the engine bay
cons: CEL will turn on, won't pass emissions, it might run lean(mine seems to run fine though so, since egr is only on during idle which it almost never idles when I drive it)

+1: Exactly.
EGR delete is no problem at all when the proper adjustments are made to your SCT tuner files. Only issue is state inspections. To get past that I just put a fake "dummy" piece of tubing inside there and always passes, no problem.
