That’s why my first try is to go back on stock tune, run my drive cycle until complete and hope the CEL doesn’t go on, then get it tested. By then, all systems besides the primary cat should be okay and ready. I’m waiting for an O2 spacer to arrive to see if my theory checks out. If not, I will need a revised 17’ tune with EVAP system enabled so I only have cat unready flagged. Steve99 reached out to me and am trying to sort this out in the coming week. Thank you all for the help!
