I am using an Accessport in my STI running about 17psi boost max with stage 1. Should I upgrade the fuel pump or injectors or both? I've read various posts regarding the STI's fuel requirements but haven't come across any using the AP.

Thanks

Would love to know also.

No. There are no other mods required for AP stage 1. You will gain NO benifit from upgrading the fuel pump and the injectors will actually make your car run really ruff. If you upgrade injectors you need to get a different ECU map.

What about for AP stage2? I've read in one post saying that the fuel system gets maxed out past 15psi and I'm already running higher boost. Opinions

I would suggest upgrading both your pump and injectors and then re-tune your car. An STi with only a Turboback will max out the injectors. Checkout the Hydra log from this post, you'll see that IDC's hit 102% at 5k RPM. :eek: http://forums.nasioc.com/forums/showpost.php?p=7567010&postcount=182
