Ok, that'd be approx 6.75 bar/99psi then. Conventional wisdom says brew pressure should be 9 bar/132psi, but hey., if it work for you that's great!
Hmmm.., well the manufacturer does put them there for a good reason.. & it's good to adjust & have control of the variables when using different espresso blends. I can think of 2 different blends I use with completely different brewing parameters!
Actually one bar may be a bit much, in this discussion it was noted that the difference is probably closer to .75 bar or so. Regardless I adjusted to what really matters, taste. Dials numbers and mathematics aside I like espresso that tastes good. I don't believe in blindly following any 'rules' about making espresso I encourage experimentation. I did dial my machine down to 7 bar per the gage and the espresso wasn't good at all. At 7.5 bar it was better but still lacking but at 7.75/7.80 the espresso is damn good and the body incredible. It seems that on my Anita the sweet spot is about 7.75 bar. When making espresso at 8-10 bar the espresso was very harsh (not bitter as in brewing too hot) with no clarity at all. I experimented across the entire range I believe I have my machine dialed in properly. I take conventional wisdom with a grain of salt!
Maybe your gauge is reading inaccurately in the way it's mounted/physically connected or "T'd" off, & it's off of what a grouphead reading portafilter gauge would read. Have you checked that Tim?, it could be off 1 - 2 bar. Doesn't really matter, because you're adjusting with your possibly inaccurate dashboard gauge., but if it were me I'd like to know. {;-) Of course taste is the all determinating factor!
7,8,9,10 bars - i'd love to be able to even get to the point where i can tweak the brew head pressure again! meantime i'm going through espresso withdrawals
right now i think i'm at what 2-3 bar?
anyways..... how do i deal with checking the vibe pump? is there a way i can check it w/o taking it out?
if i do have to replace it, can someone point me to a DIY. and a thought - IF i do replace the pump, anyone replace it with a rotary? i've searched here and hb and it sounds doable just not sure how to do it. also seen how controversial a topic it can be albeit not as controversial as brew head pressure or coffee dose in the basket.
it would be nice to do to cut down the noise
as i said the pump is not sounding the same short of me calling Simonelli- HELP!!

No I haven't checked a with a portafilter gage your right it could just be off. The espresso tastes great so I'm happy.

i just bought Oscar in September ...... i can't fathom it needing a new ulka already 2-3 shots on weekdays, maybe 4 on weekends along with an occasional cappucino...

you can put a lot of strain on your pump by having it pump without relieving the pressure. It's either leaking air somewhere because one of the seals inside became loose or the pump is not working.
Yes there is a water debit test. Hit the brew switch with no portafilter attached & measure the amount of water collected in 10 seconds. For Silvia anything at or over 90ml in that timeframe is acceptable. With my old OEM OPV 11.6bar/170psi I used to get 120 - 125 ml. With the new adjustable OPV & properly regulated brew pressure in my case 9 bar/132 - 135psi, my water debit is 110ml.
If you're all wondering, YES my espresso is excellent! {;-D

Have you called the vendor you bought it from? It may just be a faulty pump whatever the cause calling the vendor should have been move #1. I don't think tests are needed at this point, as obviously something is wrong, whatever the issue is your vendor should be able to help repair/replace.
