2017 PP with a Roush Phase 2 SC kit, and a long-tube based Kooks system to the tailpipes. I opted for the "race cat-cons" because I live in a county with visual EPA-required inspections for emissions systems.
The "post-cat" O2 sensors have been disabled in the tune (I use a Lund N-Guage, tune by Lund)
My problem is all of a sudden I cannot get the "run cycle" bits to exit cleanly. I'm getting a P0420 and a P0430. One of my banks shows as "below efficiency" and one either never completes the cycle or it too just goes to "below efficiency".
Is this a common thing? I've been using this tune for a few years without issue. Do I simply need to replace the 02 sensors or do I need to look into this "deeper"? (I have NOT reached out to Lund with a datalog or anything)
My car registration has now lapsed because I could not pass the inspection :(
