u must powerslide whilst on the turbo pad, as for the CC one, u have to have fire and then not jump of off the pad, which gives u a USF
I won't answer anything until you tell me this: Do you understand how fire works? (The reserve system, really)
Alright here we go. So the way reserves work is that every MT you do adds X amount to your total reserves. Any time you aren't boosting, they deplete every frame. Doing short MTs adds less to your reserves and should be avoided, the fuller the better. Always aim for atleast 85% of the bar or more (unless it's a corner where you need a short one to boost better.)
USFs use up all of your reserves the moment you activate it. Like Hypno said, you can't jump off of a super turbo pad because it'll cancel out your USF. Doing any kind of additional boost after USF will cancel it out (MT, landing boost, boost pads and brake I guess).
Because of this, the quality of your MTs throughout the track are very important, as the better your MTs the longer your USF will last. If you run short in comparision to other players, always make sure to check if you're doing your MTs optimally.
