Kickr power output

Has anyone else experienced their Kickr generating too much power?!? Though this doesn’t happen all the time, this somewhat intermittent issue makes a reappearance perhaps once or twice a year.

During a ride, but only if that ride is heavily uphill, the kickr will start giving me an extra 100-200watts. As wonderful as that sounds, it’s so annoying! If midway through a race, I can’t really continue. It’s very unpredictable. Could be 20mins in, 40mins in…

I’ve just done an advanced spin down to see if that cures it.

Any thoughts?

Thanks!
