inconsistent

I noticed today that first gear has a very inconsistent throttle response on my R. For example, if I hold the throttle steady at 4 to 5K RPM, it revs up and down making the bike jumpy. I was riding in sport mode but it happened the whole time. Could it be that the up-map was not installed correctly?

So the manual says that tire pressure should be roughly 30.5 psi in the front and 32 psi in the rear. However, today I noticed that the tag on the right side of the bike that contains the vin number says 33.4 psi front and 37.8 psi rear. Does anyone know why there is this discrepancy? Also...
