    TIP-In Hesitation : 05 Chevy SSR - LS2 6.0 - Automatic - Supercharged - Mild Cam

    Looking for some potential input on Tip-In hesitation.
    It doesn't seem to matter what RPM or gear (even at idle); I get a pause/hesitation at tip-in.
    It is barely noticeable when cold; however, most likely that is simply from being open loop.
    It is less prominent with the Traction Control off

    I have attached my tune, a jpg snap shot for an example and a recent 20+ minute log if that helps.
    My wide band crapped out but maybe someone knows right where to point me.

    This isn't a new thing, it has been there for since the 2012 Magnacharger, Cam install, and I have even recently upgraded the throttle body...no change.
    My last dyno was at 521rwhp - 514ftlb - 5864rpm - 129mph - at 7.12lb of boost and I am not wanting to push it any more, just trying to figure out the hesitation issue.

    If you see something or have an idea, please keep in mind, I am barely even classified as a rookie with HPT; I bought it initially for minor changes within idle, fan, gear, tire size, etc...but I am learning as I go.
