    Totally depends on what you are after and what year the truck is.

    Some trucks you can do more with and some you won't really notice as much. The later trucks with the 6 speed autos take really well to transmission changes and partly because that 4.3 already makes 300hp.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    I doubt you'd notice much then, those don't make much horsepower.

    If you want a big seat of the pants change just swap the gears. Go to something really aggressive like 4.10's or 4.56's. It'll get up to speed much faster but also reduce fuel mileage if you keep your foot in it or like to drive really fast.
