You need to monitor live data with a scan tool and watch the injector duty cycle percentage at WOT

LigHtEmUp01

can you explain to me duty cycle?

Duty cycle is supposed to be your percentage of time the injector is spraying. Anything above 80 is generally too high for safety. I was running 93% before my injector swap.

Its actually 85% where you start losing precise control, they will work above that just not the best.
