Maxed out how? On stock injectors, you're probably maxed out already. HP wise though, you've got a long way to go before you're maxed out.

Let me clarify....injectors will run past 100% duty cycle. Is this ok? For the long term, probably not. Most people target 80%. Chances are, you're either at or above 100% already. Can you get more fuel from the stock injectors? Most likely. Can you get more fuel from the stock injectors reliably in the long term? I woulnd't want to find out the answer to that question the hard way...

I'd say your at least in the high 90's %-wise.
