Is there any reason why some presets feel faster than others or is it just me?

I was Champ 3 div 3. Now im Champ 1 dive 3. I've had many games where tm8s get mad when I use quick chat then throw on purpose. Im playing the same way like I did when I was in C3. I get some tm8 thats using some random car and cant speedflip or aerial or even hit the ball. IDK what to do to get back up.

Im currently in Champ and solo queueing has not been working out do you guys think that having someone to play with will help me rank up.

Guys im in a huge slump and dont know what to do to get back to the rank I was. Help?

I don't know why but out of nowhere my movement feels really stiff and it's really affecting my gameplay i've gone down a whole rank. help.
