I use a Kbox Mini w/ a Billow V2 Mini. I've built myself a 26g-2mm-.6ohm dual coil in her. For the last week, after letting my mod sit for a while, I'll go to take a drag and it will hit really hard, to the point of burnt wick. My typical ramp-up time is almost quarted. Usually after a 2nd or 3rd pulse it'll all start hitting normal again. I've double checked my connections, have no increase in ohms and can't figure out what else is going on. I have yet to put a new build in there, but am really hoping it's not my mod. Anyone else have experience with this or have an idea what's going on?
