Yeah to be fair if you're just flashing a "this is for a stock motor" kinda tune you should be more or less OK, there's so much margin built into these motors that you're likely to still be well within the safe zone - and it sounds like you're going to do it fairly conservatively.
I mean realistically, look how many of these things are getting around with a boost tap and a poddy getting caned on 91 octane completely un-tuned.
