Default When do I need to step up to 80#inj on turbo 5.3

I currently have 60# inj on a turbo 5.3 on pump gas only, return setup @10 psi and just shy past 500rwhp. I wanna turn up the boost for more hp, how far will these 60's and meth get me before I have to step up to 80's and meth?

Sorry for the late reply. With these 60# inj, I'm at 61% inj duty, 6250 rpm, 9.5-10 psi and 11.25 AFR. How much more can I push these inj without meth and with meth?
