At that point in time Aerophagia was my biggest issue because I had my machine set to 8-10 pressure, using a 7 autoramp. My pressure was staying at 9 or above and since I was mouth taping, the air had no where to go. Even when I was not taping, the air seemed too much. Capping the air at 8.6 has been helping my Aerophagia very much.Since aerophagia is your problem, I think I'd be less inclined to tape right now. My own advice is to go back to a min pressure of 8cm (ramp up from 7cm only if you need to), and for the time being cap the max pressure at 8.6 for several days since you say that aerophagia is an issue when the pressure gets above 9cm. Yes, your AHI is going to take a hit for a while. But you need to identify how much pressure your stomach can take and then make some decisions about finding a working compromise between the pressure needed to keep the OSA under control and the pressure needed to keep the stomach happy. It may well be the case that you will feel and function better with an AHI that is usually between 2 and 3 and no aerophagia instead of an AHI < 2 and lots of aerophagia.
After plugging in this recommendation from RobySue1, I had 2-3 nights in a row that were excellent. I've now reverted back to those settings, with a Standard response rate. Everything seems to be doing just fine and I will post on this thread if I have any issues with anything. Thank you Dog Slobber for recommending this. I will run these settings for a month and touch nothing so I can collect some data.
I think my next goal is to eliminate EPR or at least try EPR 1. I've changed from level 3 to 2 (about 3 weeks back) and it's been a good experience since. So I will continue running 2. I think my thought process behind this is because it keeps my pressure more stabilized during the night.
