question on a 90 amp vs 120 amp alternator

Would going from a 90 amp to a 120 amp nipendenso style externally regulated alternator produce more current at idle and low rpm’s? Or is the boost in amperage just at the rpm’s that produce near peak alternator output?

And a second question, at what engine rpm should an alternator like those mentioned be producing near peak power?

The associated wiring has already been upgraded, I would need to up the fuse on the alternator output lead.
