When I received the email offering the P85D ludicrous upgrade, I requested additional information from Tesla, especially in comparison to the P90D. Today, I received the following response: "The Ludicrous Retrofit provides an estimated 10% increase in power over the P85D. It also provides a 0.2 second improvement on your vehicle’s current performance for both the 0-60 mph and the quarter mile time. The retrofit will not be an exact equivalent performance spec as a new P90D." This would suggest that there is minimal improvement beyond 60 mph, since the 0.2 seconds all happen below 60 mph, at least according to this email. Does this even make sense? Or am I missing something?
