Faulty O2 sensors have been known to cause RPM oscillations before so might be worth a try.

I'm also curious if changing things in the MHD tune, like throttle mapping, Stage 1 to 2, etc, resets all the adaptations or not too.
That's a good tip. In the past, I reset them all at once. You're definitely onto something though. I'll try only resetting the Lambda only and advise. I know changes maps clears codes but I don't believe it resets adaptations per se.
