For example, on capturing the GP, a TQ reduction of 7% at 120 kts will keep you on the GP without having to do much else....I forget what the power reduction is for the B412. But, by the sound of it, if the AP is making pitch changes, and the pilot hasn't been making any manual power changes, then something is not right and the mystery needs to be solved.
