Injector question

[MaxRPM]

Hey guys, I have a stock injector on my turbo p5, i'm looking to get more richer on WOT. I'm currently running at 8 psi. Just wondering if I need to upgrade my injector to hit 12psi on a SSAFC ??? If so, what injectors do you guys recommend???

Thanks
Sitha

440s from a wrx are direct drop in, should be more than enough for 12psi.

You adjust the tune on the AFC to get more fuel, you can run 12psi on the stock injectors.
