I don't like to force downshift. I do shift into L (2nd) at some stoplights when I need extra braking force. I noticed that I get much better engine braking below 1500rpm. I think boost has something to do with low effort above that.

Upshifts are different. I use my shifter kinda like a manual to control shift points.

I keep it in L all the way to the automatic shift to 2nd at 4k.
Up to S at 3500rpm.
Up to D when I reach the speed limit or 3500rpm (Whatever comes first.)

My 617 kind of struggles above 3500, otherwise I'd be choose to be at 4000 before shifting.
