I am not sure what you mean by very rich though, in comparison to a wrx or sti it is lean. obviously you need proper fueling, hopefully you would not expect me to run 11psi without it or anyone else.
I guess with any turbo car, lean = 11s. As long as one can maintain high 10s under higher boost, the 10:1 compression probably doesn't matter if you have the timing right. I just don't feel like touching my shortblock yet so even if I upgraded all the fuel components, I don't feel safe touching 10psi
