im using 1000 cc injectors
stage 2 cams
custom turbo
ms123 toyota diff
2 2jz intank fuel pumps and 1 wallbro 256.lph external
I STILL HAVE NO FUEL PSI OVER 60% THROTTLE
last dyno was 450 wheel HP
please help
thank you

sounds like ur havin a ecu feul cut for some reason.....sometimes limp mode kicks on at 60 percent throttle so you wont mess anything up....try changin ecu's and see what ya get

no fuel cut
no rev limit
rebuilt ecu
e manage ultimate pb ecu
fuel psi drop to low to fast

ok im a nissan fan im ima tell you that you should try nicoclub.com, zilvia.net , houston240sx.com and ask on there also.

I don't guess it ever occurred to you to quit trying to do wheelstands and burnouts?

I suppose that would solve the problem. . .

All that centrifugal acceleration is probably just too much for the fuel pump to overcome or something.

Either that or maybe the police are beaming slowdown beams at you from outer space.

Or maybe you have a fuel regulator that isn't working.

Or maybe a fuel cap vent is blocked.

Or maybe you need to put a pressure gauge on the rail and report your actual PSI readings so actual diagnoses might occur.

^ gauge on the rail for accurate FP monitoring FTW

How do you know you have no fuel pressure at 60% throttle?
Do you think your fuel is just cutting?
