    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.
