ASV Air Pressure Issue

I use ASVAuto and I read on lankylefty’s site that it ALWAYS should be set at 6 and 20. My issue is that when I use a full face mask it starts fine but like an hour in I get so much air push in which I can't take in so it leaks from the sides no matter how loose or how tight I have it. Is that true? Is there a way from stopping this from happening? When I use the Bleep it's fine there's 0 leaks, problem is am a mouth breather and the taping on and on it's a hassle, I'm disabled so someone else has to do it for me and you all know how burdensome that is. Is there a way around this issue? I need some help here please. Thank you all

More info.

I was using the Evora then the Air touch F20 door a good year or so. Now I can't, it's like I'm back on a V60 machine or bipap that the machine doesn't let me finish my exhaling and it starts pushing Air back to me and I can't inhale all the air and it goes out through the sides. I've try using every mask out there you've seen my list, in fact tried again the F40 last night same thing. I even lowered settings to min max ps 5 and 10 and Max min epap to 6 13 if I can remember correctly on the road ATM. Tried back the F20 nothing. Got both quattro the original and FX same, got the Lena and same. Only thing that works fine is the Bleep Eclipse but the tapping is a hassle. I don't know what to do. Don't want to try the Airsense because I have centrals. I'm desperate and don't know what else to do. I m not done exhaling when air is rushing in, also when I get to exhale fine and it isn't pushing Air as soon as I start inhaling boom it's just forced air like if I'm not breathing, I'm freaking awake I'm breathing fine. So I have to force myself to adjust to what the darn machine is doing instead of the other way around. I'm seriously desperate.
