On the other hand, if you have a 116i-engine revved up to 6000 RPM (not producing much torque, just revving high), and dump the clutch with grippy tires, you will get a high torque peak in the clutch and gearbox.

If you try the same with a higher gear, it gets even worse. The ultimate test of the clucth for slip, is to test driving in sixth gear. Clutch in, rev up, and dump the clutch. The creates a huge torque peak. A lot more than the engine can produce by flooring the throttle.
Makes sense - thank you. But are you advocating that the clutch and gearbox can handle 440nm of torque from the remap on a permanent basis?
