Tuning on a 2006 Cobalt SS with a stage III pulley, exh, and meth. Keep getting a p0101 code and the car cuts out at about 5k rpm like its hitting a limiter or something. Seems like the meth kit has something to do with it, cause I was able to get a couple 6,500 rpm pulls in just fine before we started spraying the meth on it... any ideas??

Also, any general info on tuning these pcms? This is my first one and they are alot different than most of the other pcms...
