    Injector table for 12594512 36lb Flex fuel injectors

    Factory injectors are maxed out 110%. Need to finally swap out my injectors. Wondering if anyone already has used these injectors and have a table already made I can copy over. Stock fuel system from 2004 Silverado swapping to 12594512 36lb Flex fuel injectors.

    Just make certain you use data for the EXACT same injectors operating at the exact same fuel rail pressure
    as yours. You will never obtain a good tune unless you get the correct injector data loaded into the PCM.

    gagliano7, Thanks for the information. Will pull that and see how it works. Will be doing that Friday.
