I've seen mentioned multiple times that people are considering purchasing the acceleration boost for the Model Y, but I can't find any recent information about it online, all of the articles are about a year old. Is the acceleration boost still available, and if so how do you purchase it? Is it something you have to talk to your sales advisor about? I will be getting a LR MY soon and coming from a M3P I would strongly consider the extra money for the acceleration boost if it is still a thing.
