Hey everybody. King of Hell has found a way to get a [kanye]harder, better, faster, stronger[/kanye] boost off any start, boost pad, or trick landing. The boost will propel you further, at a faster rate and last longer than other boosts. To cover the basics of boosting first:

Race start: When the 2 begins to fade away, press and hold the gas/acceleration button to gain a boost off the start of the race.

Boost pad: Drive over the pad to gain a boost.

Trick: Off any ramp, perform a trick and when your tires touch the ground, you'll gain a boost.

The basics of Uber Boosting: Between half a second and a second and a half after the boost begins, do a wheelie mid-boost (bikes only). Aside from speeding forward much faster than a regular boost, there will be a more subtle sign. The white lines that streak across the screen while doing a regular wheelie will have a rainbow-tint to them (hard to notice on Rainbow Road). The boost will end abruptly once you beigin to drift, so it's best to do this on straighter areas to gain the most out of it. Have fun boosting!
