JB4 Throwin up code signs...

Just got my jb4 installed last week and the first few runs with it was pretty fun. it wasnt long after I started getting some oscillation and a 'feathering' like symptom with the boost, didnt feel like it was hitting boost as well as it did when it was first installed. anyway, played around with a gt500 on the way back home and I get the half power sign on the dash. Pulled into the rest stop, let her cool down and took off again with the sign gone at this point. When i got home I read the codes and the last code I pulled was a 30FF. But I had more than one they were:
29DC, 30FC, 2ACB, 2ACC, 2D1D,29F3, 2ABC, 3100, 2FDB, and the 30FF. What gives??:confused: any insight would be greatly appreciated.
