TOGA Limits
On the B777, 767, 757 and probably the 737 and 747, TOGA give what ever power necessary to climb at approximately 2,000' fpm. This power setting is dynamic and is way below MCT or T.O. power. So to answer your question, there is no published TOGA power limit. Not usre how you would get TOGA power in cruise as the TOGA function is not armed with the flaps up. Simply stated there is no TOGA limit per se, just the required power to achieve the "go around thrust", which is a function of your gross weight and ambient conditions.
