EGR to remove or not remove ?

I highly doubt you would see a major improvement in anything by removing the EGR. Unless it was really screwed up/broken, leave it be.
All it does is allow some spent gas fumes back into the motor to reburn. Not exactly a performance improvement device, but doubt you'll see any seat-o-pants difference.

Keep it if you can. It helps with mileage and emissions. It does absolutely no harm to the engine's performance.

The EGR reduces NOx emissions by lowering combustion temperatures. The EGR valve only opens while at steady cruise (the highway), so you will see no gains from removing it. By displacing fuel and oxygen it also improves fuel economy.
