Check your liquid and make sure that it isn't all PG (Propylene Glycol). That gives throat hit but little vapor. VG (Vegetable Gylcerine) is what gives the most vapor but can mute flavor (not sure I agree, personally, but many proport it). I like a 50/50 blend, but 70/30 is fine too. I used to smoke a pipe, so vapor production is important to me. Voltage applied and the resistance of the coil also have a major impact. It is a learning curve, with lots and lots of research that really appeals to me. Still working toward the 'perfect vape', but it is getting better all the time. Experiment, it part of the fun and don't give up!
