How to boost up your tricks
For chili only, stop at end of the slope and press x and do a spagetti in the air.

Make your friends mad
When your character is checking his stuff before he/she goes down the slope, hold back and it feezes the game

EASY trick exp.
Ok. first find a level that your trike high score isn't very high. next go to the very bottom of that level where it is flat. Once you have done that just start jumping and doing truck drivers(L2+R2) and do that until you get tired of it. then all you have to do is cross the red line to finish.
this cheat got me 5000 trick exp on the jackrabbit level
(it helps if you have level 3 trick but you don't have to)
