Power in erg mode

Starting today am seeing much higher than anticipatd power in erg mode. Low effort, zone 1 heart rate, Zwift says ok doing 320 watts in erg mode. FTP is 315 ish slept well, but does not feel like rested legs lol. Riding Kickr v6 with zwift bike on iPad Pro. Tried resetting Kickr, leaving and reentering same workout. Anybody else?

If you’re talking about the measured power (not the power target) then I would start by either doing a factory spindown of the trainer or contacting Wahoo support.

If you’re talking about the power target being off then you should check the FTP value on your profile and make sure it’s correct.
