WTF????????
i got my car back from the shop after they took out the motor so they could put longer bolts in the headers (?????????) and charged me 2700 for the experience, the fuel pressure drops off at WOT intermittantly...
they can't seem to troubleshoot the damn thing.
the car has brand-new 255 lph pumps in-tank and external. 42lb/hr injectors and Autologic chip by Byron, stock fuel rails.

I just pulled my intank pickup out along with my inline hi-pressure 255. I was VERY surprised at the I.D. of the pickup lines & fittings on the in-line pump. I pulled off the fittings on the 255 in-line & the ID was 13/64th's (.203 inch). The in-tank pickup was not much better. I drilled everything out to 1/4 inch ID (.250). Although it doesn't seem like much, that's 20% larger diameter & area. Volume is increased by at least that much. I also found similar restrictions in the fuel filters. (stock style & high-flow)
Not saying this is your problem, just saying that I really don't know how a lot of these guys pull so much power out of these tiny fittings.
I wonder if you're fuel pump is cutting out at WOT....

that will kill a motor real fast if you have any type of power adder.
