Default What standard boost should I be running on a v4 sti?

I was only seeing 1.1 bar of boost on the way home today and thought its usually around 1.3 for the few times i've driven it.

According to this source it should be 1.1bar (16psi) std: Roojai Subaru Impreza

For those of you running 1.3+ bar, then suspect either a replacement and mapped ECU by a previous owner. Which is nice.
