Hey guys noob to the 6.7 here.

I have been running check engine light codes "P1C54 - DTC definition not found" and "P20EE - SCR NOx Catalyst efficiency below threshold bank 1" for about 50 miles as I plan to delete DPF, SCR, DEF and EGR this week.

All my temp readings have been normal, but I got out of my truck yesterday and it smelt like burning chemicals.

Should I refrain from running the truck until I finish the deletes?
