Turbo cars like to run richer in the mid 11's as more fuel is used to cool the combustion and keep detonation under boost controlled.

I totally agree. On my TT mustang @ 25PSI we are at 1000 RWH! My A/F throughout the entire curve is 11:4-11:7. Keep in mind, I am also running unleaded 109 octance VP race fuel in order to achieve this.
