What machine are we talking about here?
What did you upgrade from?
Is your dosing and tamping technique repeatable(same every time)?
My first pointer would be to aim for shorter pours(volume) and to use nothing but the 22g basket.
I personally pour around 25-30ml in around the same amount if time from a 21g basket.
Coffee taste is unique to each individual so if it tastes fine to you, drink it!
I always spend an hour or 2 once per week trying different techniques with a coffee i know well just to keep my barista juices flowing
