I just installed the kit on my OG Vetrano 2B and had a couple comments/questions.
-My first shot: I opened the paddle all the way until it was at 2 bar and then kept it steady there for around 20s. I fully opened the paddle after that but the gauge never seemed to go above 6 bar. resulting shot was soft with some acidity.
-Second shot: I added more coffee to increase the resistance. I did the same as above except it went to 8 bar. resulting shot was more aggressive but not bitter. still tasty.
What I noticed from above is that perhaps my first shot the grind was too coarse? would that be the reason why it didn't reach 8 bar after the 2 bar preinfusion? The softer taste of the first shot leads me to believe this was the case.
Another general comment is when I have the backflush disc in the portafilter, it takes a pretty long time for it to reach 8 bar (it could have always been this way as ive never had the group gauge before). The pressure gauge for the pump (not group) is at 8 bar the whole time. Would raising my rotary pump to a higher pressure speed things up?
I just want to verify that everythings good with the install.
