    Deka 80lb injectors

    I hope its ok that i post this..If you buy the deka 80 injectors do they come with the injector data or do you have to download it? I bought some off of Ebay and the seller said that they were deka siemens but im thinking they are knockoffs

    They don't come with data, that's kinda why they are so cheap.

    There might be some posts throughout the forum with data to try or maybe someone has something.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    If you go by what Injector Dynamics says. It is all in the work of the company that sells them. So E-Bay puts no work into the injectors so that is what you get ... no value. By ID or FIC and you get support. Buy EBay and you are on your own. Bad deal for buyer.

    So 300 kpa would be 43.5 psi fuel pressure

    Yes, and then if you are running the factory 58psi of fuel pressure it will be different.

    His file already has it set for 58psi as the flow rate is higher than 80 already.

    And just to be clear the tune file I posted is not one of my tunes. Just a tune file that was posted on LS1Tech that supposedly had good Deka 80 data in it. I've used that exact data in vehicles using those injectors with good results.

    Would it be best to input all of the injector data and getting the car to idle and normal drive good with the injectors before i start to tune for boost?
