My lag has also been gone for a couple of months now after the software update.

if you are still getting lag after the software update, I would reccomend getting a nitrogen leak test. I had a huge crack in my intercooler pipe (all the way across the pipe). no codes unless I really drove it hard, but the 1-2 second lag when rolling and trying to accelerate. fixed the leak and the lag went away.
