Safe injector duty cycle on stock injectors?

Was doing some logging last night and noticed I was hitting almost 90% injector duty cycle when redline in 4th gear.

I'm almost certain I'll to go pass 90% injector duty cycle if I keep going in 5th gear.

What's consider to be a "SAFE" injector duty cycle for the stock injectors?

safe should be around 85%, but you are running pretty rich so lean it out some.

I agree.. you definitely can lean it out to around 11.3 or so.. but like WBP said, 85-87% is the max duty cycle.. anything above that you run the risk of seizing an injector open or just running out of capacity.
