Chevy Thunder has the equations I think you are looking for.

Was this it?

(Maximum hp) X (brake specific fuel consumption) / # of injectors= lb/hr

it should be the square root of the new pressure divided by the old. Then take multiply that by the injector's rating at the old pressure. #lb*(New psi/Old psi)^.5 as an example, 30lb*(45psi/38psi) ^.5=32.6lb
