sorry you wasted your $80. this is a pretty well documented thing with the pc. most folks just figure that they don't ride in the 5k range anyway and just ignore it.
here's someone's email from dynojet about this:
Due to this bike having fly-by-wire, the tachometer only showing 5000rpm is a byproduct of enabling the rev Xtend function of the Power Commander. This is simply how we had to do it to include this feature. When we developed the Power Commander for the 08 model we felt having rev Xtend was an important feature to include in the unit. When we realized that the tachometer would only show 5000rpm we almost decided to not include this feature at all. But we thought it made more sense to include the feature so the end user would not have to waste $150-200 at the dealer to get an ECM upgrade that did nothing but increase the RPM.
With the Rev Xtend enabled your bike will truly go to 6200rpm but the tachometer will only show 5000. If you disable the Rev Xtend then the bike and the tachometer will go to 5600rpm.
And unless my dealer is not telling me something right, you can get a "download for the bike" that increases the rev limiter.
so basically, you could get a download from the dealer, but for the $150 or so all it would really give you is the ability for your tach to read above 5k
