setup- stock 1994 Toyota Supra turbo fuel system with 260LPH Denso fuel pump+550cc/min injectors+stock fuel pressure regulator.

everyone says car runs rich on dyno. everyone gets 11 or lower A/F, however, most people dyno with 100+octan.
I read an article saying that with same fuel set-up, lower the octan will still make car run lean/overheat. therefore, its either lower boost on street or go bigger injectors.

what do you experts think?
