I just got a TFV8 today and installed the T8 coil. I dripped a bit of juice in the airflow vents, a bit in the coils, filled the tank, closed the airflow and sucked a bit to get juice running thru the coils. I waited 10min and started at 50w, then to 100w in 10w increments. I settled at 90w.
I am generally not this careful, but these coils are expensive as hell.
Great vape on my old Snow Wolf. It is an absolute juice pig though. Wow! I bet I could go thru 6ml @90w in an hour or less.
