This recently happened to me too dude. When I read the code w/ my JB4 it says it detects a catLESS dp... like wtf? So I told them, & they said they see it from time to time. Anyway, they told me to clear it & if it comes back to get in touch w/ them again. 3 days went by & then it came back, so...
On my 22' non-tunable 3.0 Premium, I'm currently running the AA catted DP with a JB4 on map 1, that's it. The 1st day was great, then come the 2nd day it threw a "catLESS DP detected CEL" I spoke w/ them, & they said clear the code, then if it comes back to reach out. I cleared it, it was gone...
