Just because the regulator is brand new doesn't mean the gauge is accurate. I used to work for a manufacturer of pneumatic products and we'd get a case of gauges in and have anywhere from 5-20% of them be damaged. They're pretty sensitive to being bounced around. That would be the first thing I check.
Number two was already mentioned...if you poor a glass and it's coming out at such a high rate that it foams up.....poof...there goes the carbonation and the glass will taste flat. Put one or two of the restrictors in line and that will no longer be a concern.
