WRX 440 injectors

[protege520inch]

Bought these 440's to install on my P5 but the tuner said I am going to need some 550's to stay under 80% duty cycle for the horsepower I am aiming for. So for sale I have a set of 440's with O-rings. sold

When would you need these injectors? If I am going to a build of 10-12 psi, do i need these injectors?

I never pushed my stock injectos to the limit but i've read in different threads that the stock injectors run out of steam at 10psi. The 440's should be good for 230hp at a comfortable 80% duty cycle.
