There is a special cheat to make you get lots of air time on the stunt level, AND get all the keys really easy!! First, go to the SETUP menu and get the cheat menu. To get the cheat menu, press L R and Z when holding all C-buttons. Then , go into the cheat menu and turn on Levitation, Auto-Abort, Resurect in place, super speed, gravity to light, damage off, car collisions off, invincibility on. To get these codes, just start pressing buttons (IT WORKS!!).Then, go to the stunt track. If you keep on pressing the top C-button you will fly. You can get air time by just keep on going up. If you go up for 10 minutes, you get 82 air time!!! To get the keys, just go right underneath them and pres C-up and you will float up to them and get them. This does not work for the Mountain Dew can on top of the Green Giant (the really big ramp thats green) or the key in the Spike Room (the room filled with spikes).
