Message	you can increase it a little bit. But you really should have gotten 720s. The formula for new new Flow rate is real simple New CC=sqrt (new PSI/old PSI) * injector size New CC=sqrt (45/38)*555=603cc Which is right there :-) But your entire bottom end will way rich. With an AFC you can compensate for it. And while having and adjustable FPR and AFC are good for tuning they can't make up for something thats really not there. What I can suggest you dyno tune for just tuning not max power and see where you stand.
