You can run fuel cut - 1 psi.

huh?

i have no other fuel mods but a 190 pump and run 16.5 psi daily *edit* i didn't check, but i wouldn't run more than 13-14 psi if you're ATX with the 390s

now that you mention that hes auto, keep the boost below 12psi...in other words run as low as you want just dont do over 12psi. If you get manual cams and injectors youll be able to run around 15-16psi with a 190 pump.

Every car is different. I personally run 15-16psi daily without a bigger fuel pump installed yet. And I have a 16g. It has not acted up, yet.

injectors are overrated I ran 20psi on my big 16g all the time on stock injectors and a walbro 255 pump, never had a seconds problem out of the motor.

my friend ran a 7.86 @ 92 mph on stock 450 injectors and a greddy 18g @ 25 psi!!!!!!!!! his motor did finally gernade.
