Was hoping for an improvement in re-gen, but on my first drive since the update (~60 miles, 45 degrees) I didn't notice any difference! I can end up driving for 30 miles before yellow dotted line goes away. Sometimes I get the yellow warning triangle. First 10 miles regen is minimal and is only really good after I have charged at the supercharger. Maybe it will get better in the Summer.
