The torque limiting tables, what we could call that 1-4th gear torque limit isn't reflected in the dyno charts, save for the one from the second YouTube link. That one had a very noticeable flat spot at the top at 4th gear and only with the Akrapovic map.
If only the MTorque maps were to get rid of the throttle limitations, that isn't reflected on the dyno charts either. I have to agree with the guy in the first video, that the best performance seems to be with the Performance map especially considering it came free with the T800.
