Multiple issues that kind of spiraled from not knowing of things. Issue one was that I had a spacer put on my Eurojet DP thinking I could get by with that and setting the APR Stg2+ tune back to factory load levels. What I didn't know was that even with Factory Load levels, my file still disabled the sensors so the post cat was not being read with the spacer on it.
Without knowing that I had the wrong/old file, I then had the stock downpipe swapped on. It required a bung put on because the CFBA DP has 2 holes as the 3rd sensor went in the K03. K04 has all 3 sensors in the aftermarket DP, thus the OEM cat required another hole. I had this performed at a local shop still not knowing that the tune was the wrong file. Still didn't read post cat.
I call up APR and they told me that I require the newer file that enables the sensors while in stock load levels but disables them in 93, 100. So I go and had that changed to the correct file, now I got a CEL P0133. Googling that it sounded like bad sensor so I had that replaced. It's also the more expensive of the 3. Still CEL after replacing it for the same code. At this point I was going out of my mind.
I reached out to a buddy and he recommend I take it to his shop. They were able to swap on an OEM pipe that is ready to go for inspection. Doing that, it went through with zero issues. Uggggh.
