Fuel pump setup good for 800whp?

I'm new to the fuel thing but I've been doing some research and wanted to make sure I'm on the right page... I have a ls1/t56 swapped c1500 truck, now I'm going to throw in a lq9 with twin 67s and I'm planning on throwing a 22 gallon fuel cell with a Automotive a1000 fuel pump. Will I be able to use my Corvette fuel pressure regulator with this setup? Running 80lb,injectors as well. Any ideas or,opinions are welcomed

The A-1000 will be close. I ran out of pump with one on a Honda at 800, but had fairly high rail pressure. And they nose dive in flow at higher pressures.

So enough pump, just not enough injector? Base pressure & Duty cycle?

Mind if I ask what the duty cycles were & what your base pressure was?

base pressure was set to 40psi and duty cycle was in the 90% area. This was on 18psi of boost.

Did you try any higher pressures?
