I bout a stubby aio xray. I love the mod, but thank God I ordered another boro tank when I bout it, because I don't know if something is wrong with mine or if it's just generally supposed to be this loud. When I first got it and built it. I thought I was going to like, but I had to rebuild with a smaller airflow pin because it was too air with the stock one in. I took it apart rinsed out reassembled rebuilt it. Well when I started vaping again I noticed it is super super loud now. Really turbulent airflow and now it's to restricted. So I rebuilt again and again and again. Now I've taken the airflow pin out completely because no matter which one I use its to restricted and super loud. Idk what happened but no matter what I do I can't fix it. Anyone else have any problems out of there tank. Any suggestions how to fix mine? Any help would be appreciated. I'm getting an alright vape now, but the airflow is so loud I don't like to use it still and like I said it's restricted with no air flow pin installed at all?
