Here's my speculation - this is a software-only change. It is not triggered by a particular firmware or hardware build, but by a feature flag - Tesla is A/B testing with customers in the field and gathering data.
To clarify my earlier comments - At 90% battery, I've tested both with Max battery ready and Max battery turned off. In both cases I have not logged higher than 454kW.
If that truly is the case, then why did the internal Tesla documentation say to only use the model X battery in the S if the production date was on or after April 11th?
