Hi orbiter!
Which coil are you using, and is the coil wire/mesh made of SS 316 material?
Are you using the SS mode?
Is the airflow at maximum?
Do you take direct lung hits?
For how long do you inhale?
I use the same DMT/liquid ratio and mod settings with another tank, and it works nicely for me
I take hard hits 5-7 seconds, continuing inhaling after fire button is released.
Blessings
