I had mine uncorked yesterday, significant upgrade. My car is a 75D that was built June 2016. Added new setting, acceleration options - Standard or Chill.

75 and 75D variants increased performance from July 1st - software and hardware improvements?

"perf_config": "P1"
I somehow missed this entire thing. Was in the local SC (Melbourne, Australia) to get a nail in the tyre repaired. Left the SC with repaired tyre, 17.44 upgrade and a performance boost. Best puncture repair ever.

Hooray! Third attempt worked through Tesla Mobile Service. Also did a firmware update to 44 which added considerably to the time.Oh well, thought I was uncorked by Tesla Mobile Service this morning.
BUT, went for a drive later and was obvious something was not completed... was half uncorked.
Trying again tomorrow afternoon and hopefully will have success.
I thought our local folks had this down, but it appears there is still room for errors.
Such a dramatic difference. Have to get some data.
While here, also got door handles correctly adjusted to be flush with doors (had been sunken in). Adjusting the door handles took way less time than uncorking!

What, everybody bought a 75D that can be uncorked? Silly me for listening to those who advised that the RWD car drives the same!

This morning I dropped off my 60D, with stock wheels, a broken volume control wheel, and normal performance. After work I drove home a 75D, a fixed volume control, uncorked performance, and these sweet 21" wheels thanks to the referral program! Thanks Tesla, I feel like it's a different car.

If your RWD was built after June 19th, you should have the upgraded performance.

Lots of talk about performance metrics. Is there any effect on range? Intuitively one would think that higher performance requires higher rate of energy dissipation, thereby reducing the range.
Supposedly the drive unit change was mostly in the inverter to make use of high volume economy of scale inverter parts from the new model 3 engineering: fixed costs they can afford for 500,000 units a year that they couldn't afford at 100,000 units a year. I imagine the new drive units will be slightly more efficient, corked or uncorked
If I recall correctly, you need to ask them to confirm it’s performance setting is P1. If you read back a bit in this thread, the specifics are all there.
You can also take it for a quick ride with the power tools app running to confirm that your max power level is in the 300s.
As someone who has done extensive modifications to a P85... I can assure you that there really isn't much, if any, software-only headroom there. Even if there was the full support of Tesla's software team to do the software-side modifications needed, any increase in power would, at a minimum, require upgrading the battery pack to support a higher current draw... essentially would need the Ludicrous retrofit. No battery packs produced in the P85 era are capable of increased current draw without some pretty in-depth hardware modifications. As an example, the procedure for the P85D to P85D retrofit is something like 40 pages long and requires at least 4 hours of labor with two techs, plus prep time. Some older P85 batteries would require even more modification.
Additionally, if by some miracle a P85 still has an older drive unit that's never been warranty swapped (or replaced before Tesla revised the inverter), then the drive unit would need to be upgraded to handle the higher current.
To be able to handle the added torque on a launch without spinning the tires, the traction control system would need an upgrade to the current generation system as well (ESP2 + iBooster + new sensors, etc) which, by the book, would require replacing one of the main wiring harnesses in the car since, as a policy, Tesla will not modify them.
Overall, no... there is not really any software headroom left with the P85, and a performance upgrade package put out by Tesla is pretty unlikely. Overall, I'm pretty sure anyone with a RWD pre-AP car has gotten everything they'll ever get, really. People with AP1 cars are pretty much there also. With the exception of minor firmware tweaks here and there, if you own a "Classic" Model S, I wouldn't expect much of anything from Tesla anymore. Plus, every one of these cars will be out of warranty by this time next year at the latest, minus the battery and drive unit. (Extended warranties don't really count, it's basically just an expensive service contract/insurance with a decently high deductible).
My drive unit was recently upgraded because of a noise it was making.
I wonder how difficult it would be for Tesla to just offer bigger batteries and more performance for the old P85 cars. Like maybe give them your 85 and $2000 and get a 100 pack with updated software so us 85'ers don't feel left behind
