Hint: Super boost:
To get super boost, do a lot of tricks throughout the level you are playing until the little circle at the bottom left of the screen turns red and green and starts shaking. Then, go up a ramp, hold L + R and press Up, Down, Left or Right. If done correctly, you should get full boost.
