If you need more vapor, get some e-liquid with more vegetable glycerin (VG) in it. The liquids that produce a ton of vapor usually contain a higher VG blend to bring out the vapor and reduce the sweetness. As a rule of thumb, the more VG, the more vapor and less taste. On the other side, the more PG in the e-juice, the more you taste the flavors, but the less vapor production you will have. I like my e-liquid mixed with 70% PG and 30% VG, but this is a personal preference.
