Just catched up with this thread.
To keep it short: If this would not be fixed asap and I will not be able to run stable 11-13psi with V2 on my car ( without any overboost ) I will sell the unit. Word.
@Shiv: I don't like "nifty" 22psi

. Such a bug is simply not acceptable. I hope you enjoy your 4 day's off, knowing about the problems of your customers. Unbelievable.
I personally did not see such spikes and I run 2.0.2beta but I don't like to check boost permanently using the boost gauge.
Time for me to call a spade a spade.
