G8X stock turbo boost level

BIMMERPOST
     Featured on BIMMERPOST.com
Just curious what's the stock turbo boost level for a G8X m3/4 competition?

Personally I got a G82 M4 comp xdrive, I got Jb4 installed and running for the past 4 months. I've been using map2 all time with no issues.
Recently I'm interested about map6 the user adjustable map, but need to set boost level at different rpm.

As other Jb4 maps only shows +xpsi, better get a stock boost value for me to start with map6.
I remembered saw it somewhere before, but just can't find is now.

Any idea?

You can use map6 to add boost by RPM, or target a specific boost value, but using map6 requires you to know how to read your logs and make dutycycle adjustments for boost targeting. Otherwise you risk breaking something.

Understood, but just want to start with a little bit adjustment compare to map2,
Better to know stock boost level and max safe boost level so that I can have a starting point but won't cause too much damage

Doesn't the jb4 read boost? That's its whole purpose, to read and modify the map signals.
