Trying to figure out few things on my pike...

Does it have charger2?
Can i swap airshaft to 150 or 160mm and still run 29 wheel?
Trailhead app shows options for the airshaft...BUT most info i come across is pike can only be run at 140mm for 29?

Ive attached screenshots from trailhead app. Any guidance would be appreciated. Would like to run 150mm up front with my 29 setup if possible...
