Duty cycle

[1993TalonTsiAWD]

What is the duty cycle of the injectors when your pushing 15psi on stock fuel pump and stock injectors is it around the 80% no no or is it lower. Also does running a larger fuel pump with higher pressure from a AFPR lower the duty cycle or does it work in a different way.

Sorry if this question is asked or if it's somtheng I should know I was just curious and was told anything over 80% is not safe meaning if you push the 450 pass 80% they can fail or mess up. I think they run around 40-50% stock.

Correct me if I'm wrong, just trying to get this understood.

Yes.

If you just raise the fuel pressure and don't change anything else, the duty cycle will stay the same. You need to do something so that the ECU will open the injectors for less time.

You can go over 80%.

It could be anywhere from 70% to 120% at 15 psi.
