What size injectors will the 99-2000 ecu safely idle?

What size injectors will the 99-2000 ecu safely idle. Keep in mind that standard operating fuel pressure is around 60 psi on 99-05 Miatas and not 48 psi as typical on 90-97 Miatas.

Safely running 315s, no problem. This is on my 99 with automatic ECU.
Cheers,
