Was this a demo car? If it was, service may not have a record of repairs made to the vehicle before it was transferred to the first owner. As far as service is concerned that is the battery that was on the car when it was delivered.
Oh god please no lol
Summoning @P85DEE LOL!
This would generate an instant lawsuit if they did anything to my car to decrease performance AFTER I bought it and took delivery.
since installing 8.0 I've tested twice now with my car using the PowerTools for tesla app at 100% charge and max battery ready fresh off the charger the car will only hit 479-480 KW max on the app currently. Previously my car would pull 511 peak and around 505 average down to 90%!
Again I'm testing over the air with powertools app not directly via canbus so I guess it's possible changes have been made that effect powertools data as I find it hard to connect the app now, beyond that I'd need to test with canbus to confirm... hopefully I'm wrong, I would like to see others results with power tools app who have 8.0

On a serious note though, I doubt they cut the power or performance in anyone's car.
I have the v3 1088... battery, since installing 8.0 I've tested twice now with my car using the PowerTools for tesla app at 100% charge and max battery ready fresh off the charger the car will only hit 479-480 KW max on the app currently.

I'm going to test with a friends v3 1088 battery car tomorrow using PowerTools...
1/f^2 is only for the breakdown torque. Rated torque decrease as 1/f and the motor exhibits constant horsepower with increased rpm once max voltage is reached. That is what is happening on the flat portion of the power curve. Before max voltage the motor operates at constant torque. The decreasing power of the p100d curve is not an extension the p90d power curve which is what would be expected if it was rpm limited.
I said 690 hp was peak(the value on the flat part of the power curve) and not at 155 mph. But if two power curves have the same shape, specifying the peak hp's defines the relative powers at all points on the curves.
If a motor generates 690 hp for one second and another motor generates 760 hp for 0.1 seconds and 682 hp for 0.9 seconds they both average 690 hp over the second.
I just downloaded 8.0, charged up to 98% and went out and ran both Powertools and Vbox Sport. No change from 7.1 for me. Ran multiple 0-60s in 2.8 and put out near 500kw and noticed no difference in performance. I'm very confident I could go back to the track I was at on Saturday and run the same 11.1 I just did under 7.1.
Here is my data.
Vehicle: 2016 Model S P90D
Build: 1/16
Battery: 1071394-00-A
Firmware: V8
Max KWH: 487
AWHP: 653HP
SOC During Test: 88%
Mine is a early 2016 build, so based on what some of your are saying it has more power than expected.
His is a v2 and they started putting them in earlier in the year. Also, calm down. These numbers are based on data why do you say they are "foundless"?No,
Your question should be
Is your P90D V1 or V2
And if V2 how did this 1071394 Pack made it to your car that early on!!
I think most of the measurements and calculation here are foundless and assumptions at best!
I am bummed

Because we don't know. Maybe your lucky.I didn't wanna come across as abrasive!
But nobody has put forth why would my August 2015 has a "V2" when this was supposed to be one of the very early P90D?! And it was confirmed Car was Speed Lomited to 80 and no swap took place in warranty!!

Tesla servers have been slow all morning.Well thats comforting to hear... tested again this morning same result. I again had a hard time getting the app to connect and it was very laggy I suspect its related to the phone software or network now thanks to what you posted vs it being 8.0 car software issue!! I've never had a problem before with the phone app but i was on the iOS 9 software version vs iOS 10. Have you updated to iOS 10?
A canbus tester would solve all of those issues guess ill have to dig on that end as well though last I checked they didnt have an iOS app in the store just a beta tester version for those with invites / access from the developer.

The motors of both versions never reach 690hp, get that out of your head! Your calculation just don't work. And talking about breakdown torque again, why do you think the motor power decreases at the end? Because the induced Voltage goes with f^2. That limits breakdown torque if voltage is limited and at some point breakdown torque is lower than what the motor could theoretically handle.
p100d:
4945 lbs + 185lb driver = 5130lbs
p90d:
4830 lbs + 185lb driver = 5015 lbs.
The p100d has done a 10.78 sec 1/4 mile, and the time is affected by the ratio of the weights to the 1/3 power.
10.78 * (5015 / 5130)^1/3 = 10.699 seconds.
So if the p90d had the same power as the p100d it could do a quarter mile in 10.699 seconds because it weighs less.
The p90d produces 500Kw, or 670 battery horsepower.
The p90d has done the 1/4 mile in 10.804 seconds, and the time is affected by the ratio of the horsepower to the 1/3 power.
10.699 secs * (p100d power / 670hp) ^ 1/3 = 10.804 secs. Rearranging to solve for the p100d power:
670hp * (10.804 sec / 10.699 sec) ^ 3 = 689.9hp.
So the increased performance of the p100d is behaving as though the battery horsepower has increased from 670hp for the p90d to 690hp for the p100d. You'll notice that 690 hp is what they originally claimed for these motors.
Again, it doesn't matter that I'm using battery horsepower because I'm taking their ratio, and the conversion factor will cancel out.
