@Leftysmasher the advice above is spot on, and you might find this tracker useful so see the range of cars that have been uncorked.
Tesla Uncorking 75D Tracker
The other major issue has been the VIN list used to advise owners if their car can be uncorked is hopelessly inaccurate. If your car VIN range is on the tracker and you get told no, don’t take that as gospel. If you are not to far from a service centre take it in and ask them to plug the car in for the diagnostic check.
Odd. My MX last 6 digits are 0526XX. My mfr date is June 2017. I took delivery in June 2017. I got uncorked. I suggest that it's odd because it makes it appear that I have a model from earlier 2016.
