It is nice that you are one of those who are not affected by the update. There are many of us who are.
Please put yourself in our shoes... Imagine that you woke up tomorrow morning and Tesla substituted your P90 for a 70 without telling you or getting your permission. Would you be rightly upset? I think so.
As to the rated range reduction and charging speed reduction, it is very real for those of us who are affected. It has been proven several times throughout the thread, and acknowledged by Tesla.
They reduced the maximum voltage that can go into the pack, which reduced the available KW, which in turn reduced the rated range.They all are intertwined. Change one and the others change.
Wanna trade my affected S85 for your 90 straight across? (rofl)
Just my 85% of my two cents worth (Tesla took the other 15%)
