i have a 2015 silverado with a few mods including cat-less exhaust. when i scan with hptuners it shows all my readiness monitors are complete except EGR which will happen sooner or later. problem is i have p0420 and p0430 showing as permanent. and my NYS inspection is now 2 days expired. i have been researching for days about this finding all different info, most of it years old. is there anything i can do to make them go away? i had to clear the computer 3 days ago so i only have 6 drive cycles and 76 miles according to the ecu. i was hoping this would go away on its own.
EDIT:
got the truck inspected just to see if it would pass. it DID. so this entire post was useless.
mods can delete the thread or leave it for the next guy whos searching for it.
