You could try installing some sort of restrictor in the return line, just to see if that's the problem again -8 seems big for return. I have an -8 return on mine but it has a -6 to -8 adapter on the regulator when I'm using the EFI setup so it has a smaller hole in that fitting. Really should not be seeing a pressure drop, either your pump isn't up to the task or for some reason your injectors are flowing way more fuel than they should be. Have you verified your tune up?
