Am out shopping for a pre-owned Model S and have two questions. 1. What year and or VIN breakpoint did they upgrade the TPMS to display actual/individual tire PSI's. 2. I don't see any range or performance difference between the S85 and S90 batteries? Seems to me the S90 should have more range than the S85's 265 RM rating. I'm sure I'll have more as I get closer to pulling the trigger. Thanks in advance.
