If they are a forged piston then your fine.
If they are a hypereutectic then you are playing with fire at these boost levels you talked about.
About four years ago we ran them in one of our dirt circle track engines.
After the second night we pulled the engine down because we had lost compression in two holes.
We noticed the tops of these pistons had just broken away from the rest of the pistons right have the top ring land.
Keep in mind this was a flat tappet engine with a comp. ratio of 13.to 1.
I.M.O.,I would never run a hypereutectic piston in a blown or n20 application.
