I didn't know it had changed. The numbers I remember for C and C+ are both 107% power on, and 122% power off. Why I remember 122% in particular is that on one occasion I saw 120%, which of course was reported to maintenance, and the good book said no further action was required. 122% would have required a factory powertrain overhaul.
I'd be interested to read a more definitive response from esteemed members here.
