If you drive on the street....keep the EGR functional. It is a simple hole to drill in the plate. I did it on mine and it took longer to find the drill bit in the toolbox than it did to drill the hole.
If you block off the EGR the car will run lean at part throttle....possibly giving you knock. You must tell your chip burner that you won't be using the EGR and he'll tune the chip.
Drill the hole.....keep the EGR.
If the car is for the track....then nevermind.
