YZ450F‏ GYTR Power Tuner

The YZ450F Power Tuner tool does what tuning a carburetor on a non fuel-injected machine would do: provides more power, better throttle response, better fuel economy, smooth idle.  The power tuner is an easy plug-in fuel-injection and ignition tuning tool.

Quickly adjust the fuel and ignition through pre-set maps to suit riding conditions .  Saves up to 9 custom maps.
