how much boost are you running? 12.5 is relatively safe for like 3 psi but you really should be tuning for as close to 12:1 all the time as you can. 13:1 is way to lean in boost, possibly lean enough to burn pistons, 14:1 and you might as well kiss your motor good bye. 12:1 is optimum above 5psi, atleast that's what i tune for.

Stoich is 14.7, higher number is leaner and lower is richer. In boost, 13:1 can be okay for some low boost application, but its best to keep it safe and tune for 12:1 or maybe even richer (esp in cali) to 11:1 (or between there somewhere)

Well this is nice to know... I was gonna aim for 12.5:1

Turbobluemiata, Have you upgraded your fuel pump? Different disc in the fpu? Or maybe your rx7 afm needs a little adjusting.
