^^ Not necessarily BS, I've seen it done, not the smartest thing to do but has been done. The limit I would like to say is 22psi safely if boost cut doesn't hit. The 1g is more forgiving when overboosting, I would atleast put a walbro fuel pump in and you will be fine. My X ran 20psi on a 14b and no issues. It now has a 16g on it at 15psi and is running rich. I will be turning the boost up to 18psi to see if it balances out.
