Get the Power Commander. The other ones are half the price for a reason. You can only ADD fuel with the cheap ones and only in three RPM ranges (low, mid,high).

The PC you can Add and remove fuel where needed every 250 rpm's, and every 20% in the throttle position range.

You'll find out that the biggest gain is with being able to remove fuel in spots because once you start adding cams and internal mods you'll actually need less fuel in spots. There are a lot of people that complained their bikes ran worse with a cheap controller than with nothing at all
