Post Dropping fuel pressure

My fuel pressure drops as much as 12psi when I apply throttle. It will stay as low as 35psi until I push the pedal down enough to get boost.

I only noticed this problem after installing a new Trex and Walboro 255 intank pump. Can anoyone help?

BTW I have stock lines and rails, 30# injectors, 6:1 FMU, and a new Kirban Regulator set to 45psi (vacuum off).
