You are possibly leaving power on the table depending if your afr is correct or not. You are definetly leaving safety on the table, get new injectors and sell the old ones to recoupe some cost. Retune and enjoy, oh wait add a new piece to the mix to take advatage!

You don't need to get rid of your current injectors, send them off to FIC to be resized and flow matched.

Fuel Injector Connection +1

they can re-size or even if you like get rid of yours and grab some 36# or 42# injectors. Pending your fuel pressure & AFR at various rpms & maximum RPM you may or may not be leaving power on the table. As mentioned, safety is off the table right now as you are at such high duty cycle. What fuel pump(s) are you running? stock? or a 255? or what?

80% is the rule of thumb for max duty cycle. Above that and the concern is that the injectors can fail. 98% doesn't mean you're limiting power. If you don't plan on making too much more power you maybe be able to find some factory injectors with a slightly higher flow rate. What are yours now?
