What is your fuel pressure at WOT? Your pump might not be quite up to the job if the pressure is dipping. Otherwise, yeah, you might be maxing the injectors out.

Maxing out deka 80s N/A? Doubtful.

You have a Walbro 255 pump. That thing will only flow about 65% as much as the deka 80s will. You're probably out of fuel pump.

Yeah, I didn't know how to co-relate what he has to how much fuel he can suck down. I knew those were humongous injectors, but didn't know how much fuel his setup used. The 255 pump should have been a clue. Must be getting too late at night... lol
