&gt;Been doing it for years. There are literally programmer you can buy to download tunes into almost every car on the market and have been for about 30+ yrs. 
  
 The other manufacturers do that too, less performance is more reliability, and more reliability is usually happier customers and less claims. 
  
 Tesla pushed out a 10% improvement to these same cars for free a month or two ago.  I guess they realized how much this shit is actually worth.

### REPLY:
If it’s genuinely an improvement pushed out after the sale that wasn’t available before then this is great. It’s easy to see a scenario where the upgrade was held back to collect more revenue later.
