So after a couple drive cycles it seems that the codes were preventing the cat monitor from switching from incomplete. I decided to flash back to stage 2 and after another cycle the SES was back. Today I finally removed the DP fix and codes haven't popped up since. I think the fix is causing the code but was also getting me o2 readiness.
