    Scaling Injector Data?

    Hi everyone! This is honestly one of big things I feel like I cannot find the right information or I?m just overthinking it.

    I would like to get some help or anything that will point me on the right direction.

    I have ?Fuel Injector Clinic 72lbs Injectors @58psi? and they do provide the correct injector data, assuming you?re @58psi of Fuel Pressure.

    My LS swapped 350z?s fuel pressure sits at 54psi Idle/Cruise but also drops to 48psi at WOT.

    Can someone provide me a link or tell me how I can correct my injector data to match my fuel pressure?

    Or am I thinking of scaling injectors all incorrect or something?

    How is your fuel system set up? You have bigger problems other than the injector data if your pressure is dropping that much.
