Your car is overboosting and going into a valet mode. The only thing I can think of is that shiv hasn't updated the procede to the new dme software updates(hence his numbers are for previous dmes). This might also explain the MAF error codes people are getting at the start up. Since the MAF is used differently now i would assume that Shiv would have to rewrite some of the coding. But I'm no tuner, these are just my speculations...
