I when up to Mississauga ON service for my for first annual and any service performed on since I received 75D Model S. They really only did 1/2 of check off list. But I was baffled by one, they said preformed a Proformace upgrade on my motors, I ask if I had lower model like 70D or something ?and they increased it to what I had purchased ,they said no.. they said they increased proformace on the Motors , I asked more power ?said no, just better proformace on motors. I have kept up with all over air updates, and my current 2018.10.4 8bbdc66. Any ideas ?I don't have proformace model either. Car was Mgf. Dec.2016.They really did not say what I could possibly expect as far noticing anything different. And yes I did have creep mode pior to taking it in.
