You are overboosting at higher RPM compared to what the ECU wants to run, for sure, but the ECU is able to moderate it some. The run on the fuel economy map (make sure you run the +SF version of the fuel economy map available at cobbtuning.com) will disable boost control and tell us if this overboost is potentially controllable or not. The fuel economy map is not a performance map and actually, at WOT, it would be less performance than the factory map. But, it is perfectly fine to do a full WOT pulls with it (if you can do so safely).
Coldest it gets around here is 50 degrees, but i won't be seeing those temps in a long time.
