Even you must take account for Direct Injection, spike.
It cools the charge for one, it also sprays right before the end of compression (so for the most part, all you're compressing is air).
AND, they don't even reccomend premium for this engine, so I think it's safe to assume that there's wiggle room for FI once somebody gets the computer tuning down.
DI is a whole new game.......
fwiw; I'm no expert -- but I've read quite a bit on this, if that means anything -- I think you could run 5psi without breaking anything; but I wouldn't go any higher...
