    Would like opinions on this tune

    I just recently bought my HP Tuners MPVI Pro, I am using my cousins truck as a guinea pig to try and learn. It was previously tuned by another tuner using HP tuners. I am going to add the .cfg and log later, I am still trying to learn to use it. Any advice is welcomed and step by step instructions would be most helpful.

    Trying to fix spark advance and fine tune it a little better.
    There is no low end power at WOT
    A weird crackling noise almost like a backfire through the exhaust
    Should the gas mileage supposed be around 10mpg with the cam?

    The specs on the truck are
    5.3 2005 Silverado
    -LS1 Intake
    -Cold Air Intake
    -Long Tube Headers
    -X pipe with DynoMax Bullets
    -54-426-11 comp cam
    RPM Range: 1800-6800
    LSA: 112
    Duration: 222-224
    Lift .566-.568
    -2500 stall converter
    -corvette servo
