Touching power limiter at a single point in time is not what makes 0-60 or 1/4.So just checked Bjorn's videos where he did launches of the Performance and he's getting to 400KW roughly on pull from the battery and the LG pack is rated 415KW max discharge. Probably with some losses and so on, that feels like the Model 3 Performance was maxing out the battery pack already. Hence why I think a small improvement at low speeds will be due to motor changes and wheels to get the 0-60 down. They've changed where the motor tops out so that also will help hopefully with mid speed pull.
Ultimately though a car that will be a bit quicker than the last Model 3 Performance, not next level amazingly quicker. If Tesla's view is sub 3 seconds gets you to Ludicrous levels then the last car was almost there already. It only needs a slight nudge to get it over the line.
I hope to be wrong and pleasantly surprised but I think a lot of you are overhyping this and setting yourselves up to be massively disappointed.
With motors and ECU program change you can get way more power around that single peak power point. Just look at the chart of how much space from the power limiter available everywhere except a single dot.
