wtf turbo are you running?

iirc one walbro is good for near 500 rwhp

either youre running some monster turbo to be making that at 18 psi or something else is wrong

ah ninja edit with a mod list...60-1 wont max out a walbro at 18 psi, hell i dont think it even could max it out

id say youve got to look somewhere else besides the pump for the fuel problem

walboro's are good for 500hp... that's what i thought...i don't know what else can it be, every thing checks out, could it be that the pump is not delivering a 100%, if there is such a thing

You could have your filter clogged or you could be maxing the duty cycle of the injectors. What injectors are you running?

Are your fuel pumps hardwired? If not there loosing voltage at high rpm resulting in you leaning out badly.

You can wire in resistor packs and be fine.
