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?
Mods:
Utec w/stage 2 map
ABC w/stock boost restrictor pill remove
Turboback w/test pipe
Walbro 255 Fuel Pump
1G Crushed BOV
NGK BPR8

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.
