    09 yukon xl, 5.3. Looking to have tune made.

    Looking to load a better tune in to stock 5.3 yukon xl 1500. Has knn cold air. Stock exhaust with bigger muffler deleted. Like to disable. Afm and all torque management stuff and get a solid tune.. maybe up rev limiter. Make shift points higher so it doesn't go into 6th gear so quick. Firmer on shifts 1-3 gears. Any takers.. I will try to upload the stock tune file tonight after work. Ty in advance

    google and download bluecat trans tuner. Enter in your info, then it computes what you need to put into the trans tabs to tune your trans.
    The rest of what you described is what you need to start learning how to tune. No one will do it for you, for free.
    If you want a remote tuning service, i think they start abotu $400 and go up from there.
    Now if you want to learn how to tune, Then google, search and start learning as it is not a simple thing to grasp.

    Start off with this:

    Vehicle make/model/year
    Tune AND data log
    Engine/size
    Axle gear ratio / tire size
    Computer and operating system used
    Type of heads (317/243)
    Transmission
    Torque convertor stall
    intake manifold
    Intake tube / air filter
    MAP part number
    MAF part number
    Injector part number
    cam used (link to specs)
    exhaust type (long tube headers, no cats, straight piped)
    pictures of engine
    pistons
    compression
    throttle body type, size and DBW/DBC
    Fuel pressure at idle and while driving
    fuel system type, FPR, pump size, returnless or no
    ect ect
