Porpoising Altitude X-Plane 10 (Royal Duke B60)

Altitude swings wildly when throttle advanced to higher air speeds during straight & level flight.  This used to occur regularly with the Cirrus 50 jet - never did figure it out.  Have tried countering by decreasing throttle during descent, and coupled with waiting several minutes during gradually decreasing alternate climbs and dives, altitude stabilized - once.  Not having frame rate issues. Have others experienced this (in any aircraft), who can suggest a fix?

Are you in autopilot when it happens?

Yes.  Altitude setting armed and AP activated.
