IMO I would eventually get a full EGR delete down the road. That way you know for sure that all the EGR crap is for sure gone and your engine will be breathing the cleanest air it can.

I didn't think of it in that perspective but, makes sense. I already have the EGR Delete waiting for me to return home to install. I stumbled across the EGR part of my tuner just reading up on it and was curious. This is my first diesel so, I'm learning. Thanks for the clarification guys!!!!
