    Bought a 2002 2 months ago, motor shit the bed @ 129K with a oil pump failure.
    Got it swapped under warrranty for a 2004 5.3L with 110K but I can't really confirm if the ECM was swapped.

    My question is, what improvements can be made for power & efficiency that are CONFIRMED.
    I know everyone sells products to give you all kinds of claims, but I am looking for people whom
    are users that have hand calculated real numbers.

    Here's the truck , stupid clean, I couldn't pass it up for $5K , wife's Chicago area winter vehicle.

    There’s plenty of us here with a custom tune from BlackBear Performance that swear by it. Not just better hp and torque but better shifting and just incredible overall driving improvement. You won’t be disappointed. There’s a few different ways to accomplish it; if you’re lucky enough to be able to attend a tune event you can get the in person tune. I bought their autocal and can load tunes via email for both my trucks. The tunes are lifetime and anytime you want or need a change they will upgrade it.
