I just received my mega today and loaded it up with a 70pg/ 40vg juice. These are using the 2.0 ohm coil out of the box. The one thing I've noticed is that the vape is airy even with the airflow ring open just a hair. If I close the vent anymore you can't draw. Everything is tight and clean. I'm using it on a new SVD at 9 watts with a fresh 18650 efast. Is this the norm as all the reviews I've seen have been good. Could it be the bigger bore of the drip tip? Any ideas.
