Welcome to TMC. Unless you ordered a long time ago, through a referral link, model 3s in the US do not come with any form of supercharging for free, currently. I specify it this way because I have no idea of any promotions internationally, as I dont look into that.
Since your location says "freemont" under your name, I am going to assume thats in CA, so in the US.
If you ordered a long time ago through a referral link, you will need to follow up on that, but otherwise, unfortunately there isnt any.
