safc and stock injectors How many psi would i be able to boost with a safc and stock injectors? I know that most people have upgraded to rsx injectors but i dont have the money for the rsx injectors at this point. So has anyone done this or have any input on it?

well, guns ran stock injectors and a tuned vafc at 13psi with a SF fuel system
I run 9 psi with stock injectors and a SF fuel system
Speedracer32 ran 7 psi on Type S injectors and a vafc untuned
IMO..........you will be able to run 5-6 with stock injectors and a tuned vafc. If you want to run more boost, i suggest upgrading to Type S injectors. Our stock fuel pump is good for 12-13 psi. After time the stock fuel pump will fail from the stress that is placed upon it. The only real way to do it is to convert to a return set-up and Type S injectors.
There is one member that run's 440's with no return and tuned with e-manage.

Don't try this at home kids, you'll blow your motor. The stock injectors are around 75% duty cycle as they are in high RPMs....I wouldn't chance it.
