Boost pressure

[tw586]

in a recent daily blast in my MY18 GTI original, with the performance screen on the media system I observed boost pressures up ward of 28 psi, my understanding is Max boost was around 18psi, Questions is the performance monitor fibbing a little, is this transient boost to raise and maintain specific output across a wider bandwidth, or do I have a fault and should I be going back to the dealer to fix it. it has about 3k on the clock and no codes or issues
your thoughts

LOL Yeah, I was wtfing when I saw it. Would be nice if VW misused the atmospheric pressure for us.
