You shouldn't really have to cinch down the chin strap. As R_G says it should gently encourage your jaw to stay forward. As far as popping your mouth open, I found auto mode causes more problems for me. Best of luck to you!
WELCOME! to the forum.!
You shouldn't have to wear your chinstrap so tight. The idea is to gently move your jaw forward so as to help keep your mouth closed.
Hang in there for more suggestions and much success to you with your CPAP therapy and fine tuning it.
My thought is that 6 is too low for you to breathe in comfortably and you are opening your mouth to get more air in. This messes up the inhale and exhale with the machine and it all gets frustrating. If needed don't be afraid to turn the pressure up a couple of notches to 6.4 or 6.8 or 7.

I had similar problem in sleep study but I did fall asleep. I will call doctor Monday but I would appreciate direction from others who have overcome this issue. I have Phillip's Remstar Pro C-Flex with humidifier and a nasal mask. My setting is a 6. I had great difficulty falling asleep. I felt like I had to keep my mouth forced closed or bursts of air would come out. I read about an auto device from Phillips and Resmed. Should I look into another system or do I just stick with this until I get used to this. Is this simply what we must go thru when we first start? Much thanks for any help.
First night could be the hardest...
I did try a chinstrap when I first went to Nasal Pillows - i was told it was essential. I found for me the strap did not help one bit. It kept my jaw shut but did nothing to keep my lips shut. I experimented with what it took to breath through my nose while I was awake and found that tongue placement was critical for me. It seems counter-intuitive but when I got it right I found that the pressure actually locked my tongue in place holding the seal against the inside of my gums....
Its difficult to describe and can be different for different folks but it is worth persevering to see if its possible for you.
