With my last Brewtus II, I felt like the pressure ramp was a bit slow too. Maybe 10-15 seconds sometimes. I believe that doing a full descale and cleaning out the OPV helped a little, but the next thing I would have tried would be a new pump. But someone made me an offer I couldn't refuse on that machine, before I could do more testing. My dad said his Brewtus II pump pressure was basically identical.
