I’ve expressed this frustration many times about the “old” CR170 engine. Particularly with DSG. And now found it even worse in our 2010 CupraR. 1st and 2nd are useless.
Not sure why they did it that way and I figured they might have resolved it now.
Having said that, it does force you to drive on boost a lot more and I’ve found it to be much more efficient on low boost
