FI= Forced Induction. I'm doing exactly what you're looking into. We are having billet rails made up and a recirculating system fabbed. We're debating on adding the bigger injectors now with a stand alone to tune them back till the turbo gets on, or just waiting for the injectors and running stock ones for now.

I'd be interested to know the flow numbers when you get them back, may not need to change them anyway for the low boost I'm gonnna run (4-6 psi)
