    Do you think i need injectors? **Logs**

    Looking for some professional opinions here. When you look at my logs and my injector duty cycle is reaching 90+, do i need bigger injectors?

    I like to drag race and i really don`t mind upgrading, just want to know if it looks like i should.

    Thanks ahead of time for looking.

    Which injectors do you have now, the stockers?

    And, no, at 90% +, I don't think you need bigger injectors if you aren't planning on increasing the power much further in the future. However, upgrading to the LS7/LS3 injectors wouldn't hurt at all.

    Yes i have the stock injectors. How high can the injector duty cycle go before i would need injectors? What is the max % that i should keep a look out for?

    Thanks for the response.

    100% is 100%. After that they won't flow no additional. Of course, the duty cycle is just an assumption from the log, so it's not always 100% exact.
