Didn't you say a lil while back that you think something is broken in your engine?
Anyways, you have proven that you can run 22 psi and retard the snot out of the ignition timing to do it on 93 octane. It can be done. Is it advisable? The 4 tuners that I have talked to (that have also tuned my car) say "hell no". Your tuner obviously says its ok.
The ones that I have talked to all agree that you get to a certain boost level where increasing the boost more just causes too much timing to be pulled that it just isn't worth the risk of raising your EGT's like that and stressing the (originally NA high crompression) motor out. If the engine was built for huge boost then it might be a different story.
But glad yours is still running strong and I am really curious as to how your setup would fare doing hot laps on a road course. It would show just how tough this FA20 is. As it stands, here in CA, turbo guys at the track are weary of going anywhere above wastegate spring pressure. Most of us are running somewhere in the 6-9 psi on E85 or 100 octane (keeping it right around 300 whp) to have some insurance that the motor stays together for prolonged track use.
