Default Lowest fuel pressure with large injectors??

Does anyone know if there is a certain fuel pressure I should not adjust below with large injectors?

-I'm running 76.5lb (780cc I think) driven by Hondata S100 w/Boost base maps
-AEM fuel pressure reg.
-STR fuel rail
-Holly 255lph pump

Right now the fuel pressure is set to 40psi @ wot, and 32psi @ idle. It's still pretty rich so I want to make sure it would be safe to go down to 30psi @ wot if I had to, and the injectors will still run the same.

Thanks for any help!

I think RC says not to run lower than 30psi
