So I tuned my truck today with DRD tunes. Everything went good. I have to put the egt probe in tomorrow morning. And then I will be ready for a test drive. I think!

Am I supposed to unplug the egr? Leave it? And I also read a post that someone said to unplug the egr and the throttle control valve. Is this correct? I want to make sure I do everything right before I take it on a test drive.
