Jb4 CEL with catless DP
I installed a mini cat from turner Motorsport on the secondary o2 in order to eliminate the CEL. Now I’m getting a new series of codes. I initially thought that the jb4 eliminated the CEL when installed. I’m running map 2. Looking for options to fix this. Is it possible that the sensor is too far out of the exhaust stream now? Or can this be fixed with tuning?
