You might consider a staged-injector setup if your ECM can handle it. I ran RC440 injectors at 80% duty cycle on my Teg when it was turbo'd at 15psi. They did fine, except at idle, where the duty cycle and pressure made a very bad spray pattern, which caused the car to stumble and bog. A staged-injector setup uses the small injectors at idle up until the turbo kicks in, then adds your secondary injectors for the extra fuel needed.
