Hi all bin gaping for over a year now and made the move to rda builds but I'm having a big problems. I have a igo m dual coil set up running .8 ohm 28 gauge kanthal on a nemesis mod aw imr 18650. Fires well but when I take a hit I get a chronic cough and it's happening every time. But in my buddy's build I can vape fine and he's running same build. Any ideas please help
