Everything I have seen in both subforums (model 3 and Y) suggests the same thing, that AMD processor goes with new Li Ion battery.
Tesla has a real case of the "osborne effect" happening here, imo, but they didnt cause it themselves. They actually try to prevent it by not telling anyone about upgrades, which is how a company prevents the very real osborne effect consequences. This being 2022 however, you cant hide anything for very long.
For those unaware of what that is, its basically a manufacturer has "the new thing" and people want it so will no longer buy "the old thing" without consessions.
