injector duty cycle
At times under boost, my injector duty cycle is getting up to 125%.
during those times it is still holding .68 lamda, so I am not in danger of it running lean. Meth is helping with that.
I have a stage 1 ECS fuel system I still need to install. Will that solve my duty cycle problem or do I need to upgrade injectors as well?

Depends on whether fuel pressure is dropping or not
If it's not dropping then adding more fuel isn't going to help much if at all
If it is dropping then stopping it from dropping will help--you'll have to adjust airflow tables accordingly.
