As the 510 pin on the Paranormal is kind of shallow, I have to ask. Have you ever screwed down your atty until it stopped turning, and because of a gap decided to keep cranking the atty down until it sat flush? If you ever did, that's most likely your problem. I've seen it more times than I can possibly count. Very common easily fixed issue. I ask this because of the 19 mods I have, 4 of which are from Lost Vape, all running 316L perfectly in temp control. Of course I do have a gap with my favorite tank so I went to Home Depot and bought a 22mm OD, 8 mm ID, teflon washer for $0.09 and filled the gap with that washer. No more gap, not one 510 pin issue in 4 years of vaping.
