My buddy just got a 2012 WR450. I searched, but can't seem to find if this trick is still do-able on a 2012 WR with FI.

Is the "grey wire" trick still available on 2012 WR450?

Thanks for any info guys (and girls!).

don't think so as its all done in the ecu, which you need to change to the competition one (along with GYTR tuner) to unleash the power
