2015 WRX's built tougher than Ford...

So, the 15 WRX's have a tendency to overboost from what I am seeing... The factory tune has it set for 15.9 peak, but look at some of these....

Happens on the STi too unfortunately, my buddy has hit 22.5 at one point on his 2015... Subaru is aware of this and has said it's not a concern...but they may release an updated base map at some point.

Not a concern? Really?
 
The boost may depend on the load and what gear you are in. Also, as long as timing is conservative during the boost spike, it should be fine. I would be curious if anyone can data log this when it happens and see whats going on. Also curious what the AFRs are when this happens. If its not setting an over boost code, I probably wouldn't stress about it.

Thats the problem. No data yet to show for this.
