    Need help: ly6 Lunati Cam Ls3 Intake Ls3 Heads K&N Cold Air Longtube full exhaust

    I've just recently purchased a VCM pro and need to figure some things out to get this truck running again. I have a 2007 Vortec Max ext cab with the following aftermarket swaps:

    Lunati Voodoo Cam:

    Advertised Duration (Int/Exh): 262/273
    Duration @ .050 (Int/Exh): 212/223
    Gross Valve Lift (Int/Exh): .530"/.549"
    LSA/ICL: 112/108
    Valve Lash (Int/Exh): Hyd/Hyd
    RPM Range: 1600-6200

    LS3 Heads:
    Combustion chamber volume 64cc
    Intake runner volume 255cc
    seat pressure closed 145
    seat pressure w/o inner spring closed 115
    intake valve dia 2.165 in
    Exhaust valve dia 1.600 in
    Valve springs up to .680 lift
    intake valve angle 45 deg
    exhaust valve angle 45 deg
    valve seats machine style 3-angle

    Gm Performance Ls3 Intake Manifold:

    GM Performance Ls3 Throttle Body:
    90MM

    K&N Cold Air Intake:

    Ls3 Rocker Arms:
    Comp Cams Trunion Kit

    EPP Performance Chromoly Pushrods:
    .080" Wall
    5/16" Dia
    7.400" Length

    Ls2 Timing Cover:

    Range Technology AFM Disabler:

    Performance oem ly6 lifters:

    Basically I'm curious what I should be looking to tune, and what exactly I need to do to remove the VVT from the PCM. Any help is greatly appreciated!
