It appears that the upgrade only covers the fuse replacement allowing more power to be passed through it, thus the faster 0.2s acceleration. It doesn't include the battery upgrade to 90 kWh. The badging will add an underline to the existing P85D badge to indicate the ludicrous upgrade. The price isn't given but they're asking for a $500 pre-order nonrefundable deposit before we even know how much it will cost.
My sense is that this will be a good value investment as the increase in resale value will likely outweigh the cost of the upgrade.
We already know it's a final total of $5,000. It's right there on the Tesla site.
