I just got a Penelope and a oddy drip mode. I wired them up and have 1.5 ohm and 2 ohm respective. I am running them on provari's voltage 3.5 and 4.5 respective. The taste is amazing. My problem is the vapor production. It is no more than my egos with the stardust. I am looking for a CLOUD OF VAPOR. Im running Boba and other high vg juice. What am I missing????
