I took delivery of my new Tesla Model S Performance with Ludicrous Mode yesterday but have a question. I don't see Ludicrous Mode listed anywhere in the settings. I see Chill, Sport, Insane and Insane + but no Ludicrous. The rear of the car says Dual Motor only. Is this correct or was the Ludicrous mode not installed on the car? My friend has one and his says Ludicrous +. It seems that a Ludicrous upgrade it should say Ludicrous. The owners manual even states Insane + and Ludicrous +. The car does not go 0-60 in 2.4 seconds either, rather more like low 3's. Does anybody have any information on this? Thank you.
