How much boost on stock injectors

[snidly_wiplash]

i wanna go witha larger turbo but am kinda concerned with how much boost is safe to run. Im going probably evo III16g or Big t28.. if i get a high flow fuel pump how much boost is safe before i need injectors nad then a SAFC

or you could just search and find an answer of 15-17 depending on your particular car... I ran 17 psi on a 2g with a 16g and 190 pump safely.

17psi tuned or untuned?

You can run 17psi untuned on the stock T25, but trying to up the boost on an aftermarket turbo without having some engine management in place is putting the cart before the horse. Perhaps instead of starting with an S-AFC, you could consider the MAF Translator setup that will both increase airflow and thus power potential while allowing you to tune at the same time. If you'd like to discuss further, feel free to give us a call.
