is gsr fuel pump sufficient for 350 h.p.?

[egvtec]

ok i am running uberdata and im ready to go to the dyno. my fuel pressure is still stock. and i am wondering if it necessary to upgrade before the tune since i am still running stock fuel pressure?

i would replace it. whats a pump cost $80? Jeff has them in stock when you go down to tune.

walbro 190 or 255?

[PM-Performance]

for the price they are just go with the 255 hi pressure. and be done with it. then you knwo you can grow into it rather than out of it

[iLLeFFeKt CiViC]

if you dont have already make sure you get a good fuel pressure regulator. with that hi flow 255 pump it will run very very rich at idle and low rpm at least thats what i've seen with dsm motors.
