Ok, so I have a MM3 from Ray with the EGR tuning. When I got it I was told to unplug the EGR. Lately I feel like I've been reading that you just leave it and the throttle valve plugged in now. So my question is what do I do? I went ahead and replugged them in. Will this make the EGR work again or is it shut off by the tuning? If its shut off, why would I be getting a reading from it on the MM3 when I go to the EGR parameters? TIA
