Good info. It’s hitting a brick wall after (or maybe just before) the 1/8 mile. 0-60 looks good though! My model 3 performance traps 94-95 mph in the 1/8 and 117-118 in the 1/4 for reference so you should be picking up way more mph on the back half of the track.
Something is wrong. That trap speed is lower than a non GT car. It should be 110-115 mph with a GT. It would be odd that not using unbridled causes that.
Check PlugShare and see if there are CCS or J-1772 chargers near the track. It will take a few hours to charge to 100% due to the cliff at 80%.
