There probably won't be a real solution for this, as VW likely doesn't consider the problem important enough to adjust the TCU software in one of the next updates.
But there's at least a workaround: Use the gas pedal instead of the "+" button to accelerate, and simply press "Set" when you reach the desired speed... Or is your right foot completely numb when you drive with GRA

?
Initially, I was also disappointed with the GRA's inadequate acceleration capabilities, but after about a year, I didn't notice it anymore...

Sure.
Here is the translation of the text from German to English:
"Guste" is a German word that means "gust" or "gust of wind." It can also be used as a verb, meaning "to gust" or "to blow."
Here are some examples of how the word "Guste" can be used:
* "Der Guste wehte stark." (The gust of wind blew strongly.)
* "Der Wind gustete." (The wind gusted.)
* "Ich gustete." (I gusted.)
I hope this helps!
