Default Help with my c5 fuel setup

car is a 2000, vortech si head unit, jam cam, fic 1000's, straight e85. im on a relatively safe tune 8if I had to guess around 650whp), but im seeing 97% duty cycle on my injectors so im wondering if i have an issue somewhere as the 1000's should be large enough to handle that according to every fueling calculator online. Stock in tank pump, and a DW350 on a Hobbs switch, ptfe lines, wix filter/regulator, pics have been attached.

could my rails be restricting me due to the small intake in which my an line is feeding? are the lines ran correctly? what's needed to solve this issue?

1000cc injectors rate at 43psi or 3bar and run with that filter if it does see 58psi or 4bar will support about 940HP NA and about 780HP supercharged with boost reference pressure. Knowing this and not enough about your fuel system, I'd say you next step is to put a pressure gauge on your fuel rail and make sure it holds it at max effort.
