long as the MAF, injectors, regulator and pump can still operate at the target bhp and the AFR, boost & engine temperature and timing are controlled within safe zones before detonation by altering fuel/ign mapping or parameters, fuel octane and upgraded cooling, the k11 standard pistons, rod and crank can easily endure ie. 10psi on a trackday with the right upgrades like on mine. dunno what the absolute safe limit is
