Default Magnetti Morelli fuel injection

I have the MM fule injection and installed a 98" kit on my bike. Also put a PCIIIusb and had a custom map done. It runs great but the dyno tech told me that he had to jack the fuel numbers way up. He thought maybe I had a fuel leak in the tank but I was wondering if I'm just getting to the limit of the injectors. I have the red injectors which are supposed to be the bigger ones. Could I be at the limit and if so, is there something I can/should do short of replacing the whole system?

The stock MM injectors should be fine for a 98" build. Take a look at some of the canned maps offered by Dynojet. You'll see they all have fairly high fuel numbers.
