Turn it up. On the Itaste vv you have settings for Voltage AND wattage. Make sure your Volts are around 3.6 and the Watts are around 9.0 - 10. The new BVC coils need a little more power to get a good vape. If you still aren't getting vapor turn it up a little more. If you still not getting vapor try a new coil, then different juice, clean the mini to make sure the air holes are not clogged. If you are still not getting vapor try the tank on someone elses mod. Don't give up! Keep trying till you get what you want. The beginning switch to vaping can be expensive and time consuming, and can also have a steep learning curve. Some take to it quicker than others. Be patient and you'll get your perfect vape soon!
Edit: I guess I misunderstood your post, your problem is that the coil is making snaps and pops? That is normal for any coil burning juice.
You are right, if you turn it down you will get less popping, keep the volts around 3.6 and the watts down to about 7 or 8 you should get less popping. I misunderstood your post and thought you were getting small vapor.
It is possible because you can set both and use whichever you want. I think it's best to have them both set and then can switch easily depending on what atomizer you are using.
Yes, it is possible to enter a setting for both values, but only one of those settings will be in effect. This is not what you stated in your earlier posts.
I wasn't trying to single anyone out, but your earlier posts were misleading if you do, indeed, understand that only one setting is relevant at a time.
