Just ordered my tuner and new exhaust which should arrive this week sometime. I've been trying to read and look up on what steps it takes to delete my truck. I am planning on leaving the EGR and throttle valve on for now. I know I need to flash the truck ECM first before I start removing the exhaust. Is there anything I need to do to the EGR like unplugging it or should I just leave it alone. I bought the MM3 from DRD and I'm pretty sure Ray's tunes turn off the EGR. I guess does anyone have an instruction list on the steps it takes to do the deletes? Any help is appreciated, thanks!
