depending on the shift kit level you put in and the raised shift pressure of the tune, then yes.
Either retune or adjust the shift kit.
Depending on how the jerk around is, Accumulator can have rough spots in there/crud and cause the pistons to catch abit.
But usually just lean towards "bang/screetch mode" of shift kit.. plus the higher pressure levels of the tune being the issue.

Think you're right just wasn't expecting all that lol

it takes some getting used to. I think its better for the transmission to shift faster because there is less slipping. if you find a local tuner or pickup a dhp programmer you can change how fast/hard it shifts, as well as many other things.

I wonder what the AFR is now on those things...close to 11:1? lol

I should look and see what they had it set to, I ran a zzp 1.0 pcm for a while and downloaded the tune when I got a dhp.
I looked it up, I'm pretty sure this is zzp's tune
