I noticed that mine likes to bounce. When there is a load, the tach drops. When the control system tries to recover, it overshoots. Then it realizes it went too high and comes back down. The A/C does this when it turns on. If I turn the bass on the radio up, it'll follow the music.

On a side note, I did notice that there's a certain temperature that my engine doesn't like. The problem is that it's a little above ambient for this time of year. When the engine's at this temperature (at start up), it revs really low. Every so often, it's so low that it feels like it's getting ready to stall. It's fine when I give it some gas, but it doesn't like to idle properly. Once the engine warms up, it's fine though.
