Ok... I just got a new Povari and DCT tank (3ohms). How do you setup the best voltage for it? I read somewhere to add 2 to your ohm reading and adjust to taste? So in my case, 5 is the number to start with? With my 6ml DCT, 5v works great! but for my 3.5ml (also 3 ohms) DCT tank, it sucks! It taste like sour and very dry! I tried to lower it at around 3.5 and while it taste ok, there are not enough vapor coming out of it. Thanks
