I've read that there it has some effect on range mode - that if you're looking for the best possible range, that you should lower it to sport. Is it true? Heck, I don't know. It seems like the sort of thing that Tesla should clarify.
Only thing I could think of is perhaps the throttle would be less sensitive without ludicrous on. I just had a loaner 85D and it was harder to accidentally accelerate faster than you expected on that car
Knowing that I paid $10,000 for that little blue soft key makes it difficult to ever deactivate. As far as I can tell it has no direct impact on range. Max battery power does as it heats the pack.
