Peak boost

Ive noticed that my 2018 wrx reads 23.4 PSI for peak boost on my boost gauge. Does that mean that is the max boost it will hit or is that the most boost the car has experienced? I haven’t even came close to that myself as I’ve been granny driving my car breaking it in still. Kinda worried because when I took delivery of my new car 2 weeks ago it was reading that, could one of the lot attendents abused it or?

That is the max boost it's hit. Even if for a split second.
Should I be worried that my car had that reading when I took delivery of it ??
It's not going to ruin the car to floor it every once in a while.
my car read high like that too, i was concerned for awhile too but the stock tune is kind of strange with the peak boost. i dont think that peak boost being high is any guarantee that it was taken on a joy ride.

My peak has been 28.6 so you should be good.
