So I bought it last night. Also, the android version of the tesla app is now updated so you can purchase through the app.
You definitely feel the improved power. I charged to 90% and did some before/after runs with the battery at around 40C. Not fully scientific but I do have a canbus reader with scanmytesla. Measured 4.5-4.2s 0-100 km/h before and after 3.9-3.5s. Obviously there is a pretty big margin of error there, but it for sure pulls harder.
Whether it's worth it is up to you and if you have some extra cash. I wouldn't dip into the kids college fund for this, but if you wished you had the chance to buy a P3D- and couldn't stomach the 20k hit you would take trading in (assuming you could even find a P3D-), this is pretty good value.
Plus my gut says this purchase won't be a one time thing and I'm hoping this will lead to further improvements down the road, just like how FSD adds more features as they come available....
But of course, YMMV....
