I have a 07.5 cummins 6.7 that is throwing EGR codes. I just got a Smarty Jr and I didn't see any posts about NC emissions and I would like to delete the EGR and DPF. I know I can pass the visual but from what I'm told they plug a computer into the obd2 port . Does anyone know if I'll pass that part of it? I live in guilford county. Any help would be greatly appreciated.
