Well, it was happened it in my dreams last night! but, I think MX90D version got potential for more power. All Tesla have to do is unlock it through software upgrade. I love my MX 90D, and don't want to upgrade any time soon, but I wish to have a little more power. Of course Tesla doesn't want to get close to P90D territory, but 0.5 sec for 10 to 15K, I would imagine there are a lot of owners would consider that option! it's extra revenue for Tesla.
