Default Would 550cc injectors be good for 15-20psi??

I am debating on if i should just keep my 550's that i have now or should i get something bigger, i was thinking about 780's. Heres my setup

Golden Eagle Ls block
Eagle Rods
Wiesco Pistions
PnP Ls Head w/ Crower 402t and valvetrain
Garrett t4OE w/ SP mani/dp 3" all the way
Walboro 255
skunk2 mani w/ 74mm tb

My plan is 15psi+ Should i keep the 550's?? Or upgrade?? Any help from the big turbo guys would be nice. thanks

550's usally max out at or around 325-350. If your looking to make more then I would def upgrade.

550's are good for about 350whp. I have seen some people push them close to 400whp, but I would not recommend it.
