On my overhead display I am getting a "Catlyst full service required" warning along with an alert bell. I have done the EGR delete and taken off the DPF and replaced with a straight pipe without the oxygen sensors. Everything is unplugged per the Smarty insturctions. I have a Smarty ME (I lucked out and purchased it before they had to discontinue the ME file) set on I believe 3 (tune with timing). I have had the stuff removed for 14K miles. Why would I be getting this message? How do I get it to go away?
