you know when your boost bar turns red when you keep doing flips and stuff and get the bar beside it(the green one) to fill up again while the red one is still going that will start a level 2 boost do flips and stuff to fill up the green bar while the level 2 boos is still going to get level 3 boost simple as that works up to level 5 boost.
