Hi, I am running the watt atm at 8.5 and the volts at 4.8 and it isn't tasting burnt. But I want more vapor and want to put the watts up higher, or the volts vise versa. And the PG/VG ratio is 50/50. and No only when I turn it up but I want to have a higher wattage setting or higher voltage to get more vapor. I am currently vaping a blueberry with 18mg nicotine.
