Maximum injectors for SAFC??

I have a SAFC installed in my S4, and im about to finish my 6 port turbo. I have 4 550cc injectors im planning on using, and im sure that the SAFC would be able to control them, but in case i decide to go with bigger injectors in the future. What is the max injector that the SAFC can successfully control?

Does anyone know about this? I was about to pick up some 2000cc just cuz they are sooo cheap. I know its totally unnecessary on my NA but I plan on going turbo by next years SS

well the safc can only +/- so much fuel so i would have to say it depends on your fuel air ratio when you get the car running, and start boosting on the car. so to say a max injector it could handle i would say it would be unlimited because of this- i could have a big turbo street port engine with 2000cc injectors and im running -15% on the safc and seeing 13 afr. or i could have this a small turbo with 550cc injectors and running the injectors at -15% on the safc and running 13 afr. its still the same value but just different out puts of horsepower. im no expert but thats what i understand. i hope my advice helps a little and someone may correct me if i am wrong with my thinking
