Tanks to try, Evod, Vision Victory. when you first start vaping a new coil, start at lowest volts, after 15-20 vapes, the wick & coil should be broke in. you can start turning up volts, this should help with burnt taste, but if the E-Juice is thick, it cant wick fast enough, so add a couple drops of bottled water to thin out the juice, start with only a few drops of water Shake & vape. I vape at 1.1 ohm - 1.8 ohm Coils on evods & Victory's after break in at 4.0 volts to 4.2 volts. if the wick is getting the eliquid fast enough it can be turned up. never on a new wick as you are burning the wick & taste will stay, always break in a wick before turning up volts.
