You shouldn't be concerned about early BOV actuation causing any damage since it vents prior to the MAF sensor.
While the car is idling, is the BOV open? Also I'd check the BOV and WG are properly installed and have their O-rings properly installed (I can't remember if both have an O-ring).

I am on a speed density tune so to my understanding it is not using MAF readings but rather preset values are input in place of the MAF. Before with the 8 PSI spring my BOV was open at idle, now with the 12 it is closed. I am positive that the O-Ring on my BOV is in place correctly, I honestly don't remember either if there was one on the wastegate. In regards to the low IAM, another thing I forgot to mention is that I had what I believe to be a Cam Angle Sensor wire touching my downpipe(which was wrapped). I've since threw a layer of electrical wire and gold foil around the wire that was touching.
