^^ exactly. dropping fuel pressure can be tuned around all day for safe A/Fs, so long as the pressure doesnt drop too low for the power and injector size. Its very possible that is the scenario occurring in my car and many other boosted Z's.

Has anyone else actually monitored fuel pressure at the rails above 500whp?
