For those out there with the RJC PP, are there BIG performance gains if you don't drill the hole for the EGR? Will anything on the car not work properly if you don't drill the hole?

Thanks

Drilling the hole will neither gain nor loose anythig performance wise.
Not drilling it of course will render the EGR non functional (which may or may not be a smog issue, depending on what your local laws and limits are).

Drilling it will allow use of the EGR, if you do need it someday for a smog inspection, but will not hurt performance with it functioning properly.
