Impreza GC8 Bad injectors or tune?

Tuning issues on my GC8
Ive got a 95 jdm ej20 motor in my car. Field SFC Hyper II fuel computer tuned to run a little rich to make the car work right on american gas. I'm getting some bad stutter (also known as knock :-( ) all over the range. It's weird tho, sometimes the car will run beautifully and pull really hard, and sometimes it will stutter at anything over 7 p.s.i.
I was thinking this might be a fuel problem. I'm going to upgrade my injectors (any reccomendations on what flow rating to go with) and put on an electric boost controller and have it tuned.
Do you think this will help my problem?
