The injectors can't be that far off of optimal though. It's a supercharger, so there isn't any way to regulate boost without a physical change in the drive ratio. it's not like limiting boost with a wastegate to keep from getting too lean. The boost now is the same boost with the larger injectors, so all that will likely change is the air/fuel ratio unless the pulley will get swapped out at the same time. So it can't be too far off if it isn't on the dangerous side of lean. So while there is probably some good power gains from larger injectors, it probably won't be too much.
