Yes the code most likely is a Delayed reading code for the front 02s as the response is slower as they are farther down stream and deleting the CEL code is a must in the programming, I had it happen to mine in about 20 miles, just returned to tuner and he did twenty seconds worth of hp tuning as he knew right where to go..... Some never have the code on some headers is the deal though supposedly.
