I have a regular MAP tank with a 3.3ohm reading. I'm having a hard time getting a nice vape from it. I'm using it on a ProVari and have vaped it at every setting from 3.5V all the way up to 5V (yuck, burnt). When I got the MAP I didn't wash it or do anything other than fill it up to 3/4 full. I'm not getting much flavor at any setting. I'm wondering if I should empty it and wash the wicks and coil?? Any tips or advice would be great, thank you
