That is weird, I have both JB4 and Procede and I believe they both have DP fix built-in, unless they automatically clear all the cat codes, it shouldn't have thrown codes right after I switched. I have reset ECU couple times, also check if my pre-o2 sensors were correctly installed (which I think they are, black wire goes to long dp, grey goes to the shorter one). codes keep coming back. only other thought is that my o2 sensors have gone bad and considering my car is almost 7yrs old, this could be the reason. I emailed Cobb and waiting for their response before replacing my o2 sensors.
