From what i've read, around 1700 psi is the point where n55 will start misfiring at WOT if rail pressure drops below that point. I suspect rail pressure is your issue; your moving enough air that your HPFP can no longer keep up.
hey man updated the link if you wanted to look over that specific 3rd gear pull i made lmk if you see the same hpfp issue there or if something else doesn't look right
