Knuckles super speed with select items

[Yohan1044]

When Knuckles is using an item which uses a select set of item-legs animations (cracker launcher, fire flower when but only when holding A, ect.), when Knuckles moves forwards or backwards, when he hits max acceleration, his speed increases dramatically.

If you use Sonic's Motion file, this problem goes away.

Perhaps it's a misvaluing in his PSA? Lyn has a similar glitch with her teleportation in few stages. It could be a PSA problem also. But if the FitSonicMotionEtc.pac makes it go away then alright.
Edit: Perhaps tweaking his movement upon carrying an item should be dumbed down to average speed.

Made a video documenting the bug.

Cool video. I'd've recommended the training room myself... as there's a lot more ground.
Run forwards/backwards with the cracker launcher.
Run forwards/ backwards with the fire flower
Run forwards/backards with the fire flower while holding A.
