Mares Abyss Octo, brand new, not breathing well
It's possible that the perceived free flow problem is causing a more general lack of faith with the reg?
A correctly set up reg will never be too far away from free flowing in that transition from air to water - just as you dive in. This is not uncommon and shouldn't necessarily be determined to be a fault. Some manufacturers have gotten around this issue by allowing the user to switch the 2nd stage to a less sensitive setting (small knob on side 'pre-drive' & 'dive'). This means the reg can still be set up correctly but effectively put into an incorrect (for diving) mode while you are bobbing around on the surface getting ready to go down.
The fact that the abyss doesn't have this mode doesn't mean it isn't working right. If your shop adjust the sensitivity too far, they are going to make it harder to breath with. I have a couple of Abyss and sometimes experience small free flow. Nothing to worry about. You can look it up but the reg has been down to some record breaking depths without issue.
You haven't said which is your main reg - but the poseidon system runs a much higher pressure between 1st and second stage. You absolutely should not use this octo with poseidon, unless it has been ok'd by a authorized poseidon dealership.
In summary I can't see that your two problems are linked.
