    98 to 2000 Suburban 7.4L 4L80E 2WD calibration

    1998_Silverad0_74_4L80E_1306075053.hpt
    I am looking for a calibration for a 98 to 2000 2WD Suburban with a 7.4L and a 4L80E.
    I have searched the tune repository and have only come up with 4x4 versions.
    I could start from there but would need to convert from 4x4 to 2WD.
    Attached is the tune from the tune repository that I believe is for a 4x4. Can someone confirm this. What is required to use for a 2WD.
    I am converting it from 97 to later so that I can modify the injector size and tune it.
    Thanks
