No one can give you a number of "maximum safe boost" because theres no way to really know how long the internals will last and peoples definition of "safe" varies. We know that 8psi seems ok to run for long term, 10psi shouldn't be much worse. Sam/GTM seem to plan on running 10psi here, so they feel its a safe enough level for the engine to last reasonably long with their tuning.
