Got a vivi nova today (came with my new vv mod). I have only used bcc's and rda's/rba's till now and I am having probs from the start with it. I am getting Burnt hits with the stock coil at 3.0 ohms and lowest setting of 3.0 volts. I can get maybe a 1 sec puff, then burnt taste. My question is, should I rebuild Right away? I do the tip and swirl thing and all, but do use high VG DIY liquids. Are there flavor wicks I can take out like the PT's and such? Using about 85/15 VG/PG liquid. BTW, it tastes wonderful with my rda. Thanks for any help I can get.
