I'm fairly confident mine is a stealth. The reason I say this is the door jamb plate list the wheel size as 18". I would assume if it was the PUP version they would be listed as 20s. Brake calipers are "silver" or, more appropriately, metallic in color. They're definitely not black or red.I see two possibilities: OP has a Stealth, or an earlier owner modified a Performance with the PUP.
As Sklith mentioned, even though the PUP was "standard" by 2019 and you couldn't order a Stealth online, you could order one through a sales rep. Also, some of their demo cars were Stealths that would get sold at the end of a quarter. You could see them every now on the inventory page, although they tended to disappear quickly.
However, OP's car might have come with PUP. Mine did in Nov 2018. I would have preferred a Stealth, but the option was no longer listed when I ordered online. However, at the time Tesla was out of spoilers and badges, so I didn't get those (at least not at first; they did put the spoiler on months later; and I asked them not to put the badge on). And the first thing I did to the car was sell the 20" wheels and buy 18"s. So while my car came with a PUP, at least at one point it matched the OP's description.
OP, what color are your brake calipers? (Of course a previous owner could have painted them, but let's start by assuming that didn't happen). The Stealth came with black calipers, the PUP came with red. Note that the upgraded brakes shouldn't matter for normal driving; the regular brakes are already stronger than the tires for infrequent emergency stops. The upgraded brakes are primarily for track driving, to keep them from overheating longer when in constant use.
No Dual Motor badge and corresponding red line on the back of the vehicle. I assumed the previous owner debadged it (I know a lot of Bimmer owners do that).
