If your ecu picked up some noise on the knock sensors when you shot the juice it may have shifted to the low octane timing table and remembered that in volatile memory. I only say this because torque management doesn't use volatile memory and shouldn't change its state or function with the battery disconnected as you describe. That sounds like a stored code that got cleared or adaptive strategies that got reset.
If you can post up a tune file(.hpt) with a log file(.hpl) I would be happy to take a look and give you my honest opinion.
And yes C5 and C6 torque management are different.
