Default newb injector question

I have just installed my f13 cam and headers. the car made 390rwhp and 380rwtq. However the injectors are maxed out at 111% duty cycle. I have a 2002. What do you guys recommend? Sorry I installed my cam myself, but i'm a total tard when it comes to fuel injection.

That is strange.....
An '00 with 26 lbs injectors should be able to handle up to 380ish. You definitely should be able to get 425+ out of the 28.8's.
......did they gauge/test it or just look at a math table ? - that might be the issue.

I can believe your stock injectors were maxed at 390rwhp. that is 470+ engine, and they were designed for 325. Go here to find out what injector you "NEED" to run.
