    I have the injector setting data for the LS3 Fast 39# injector. It is supposed to be the stock LS3 injector. I will look in the tune repository and compare the injector data I have to a stock LS3 corvette or LS3 Camaro to see if it is the same.

    Nope, sorry, I went back in and looked at it and it is NOT the correct injector data. I have the data at home. I will get it tonight for you.

    The rest of the tune is useless to you. That was a starter SDOL tune for my 408 setup. DO NOT try and use any of the data in that tune.

    Do you have a Manifold/Boost Reference Fuel Pressure Regulator?

    The values in that tune are ALL off and wrong. Not even remotely close.

    Okay, here's an Excel file that has the 2006 Z06 calibration data converted to Gen3 format. Just copy/paste the highlighted yellow cells.

    FYI, the LS7 and LS3 injector are the same.
