Hi all, 2 month old Silvia and Rocky combo. But learning fast from all this wealth of information on this site.
My Silvia model is the newer 2007 model.
I was wonder whether adjusting the OPV is worth it?
I hear that 9 bars in the group head is the ideal? why is that?
It looks fairly simple how to change... (untighten locking nut and screw other nut out to decrease pressure and then re-tighten locking nut?)
If I do this, does it void my warrenty?
Also I guess I have to get a PF pressure gauge from coffee parts to see what the pressure is?

Thank you for your help.
