Blade Root,
Normal convention is to remain with the torques. No doubt you have found that the BK's normally torque out well before temping out, so we monitor torques as the primary limit.
If your interested, the temperature difference is due to one of the ECS valves sticking. There is one on each donk feeding bleed air into the aircon. If one is not opening fully then the other pumps more bleed air thereby getting hotter.
Otherwise a great aircon and a top machine.
Cheers
