Kinda in the same boat, though it's getting better. I can get huge clouds of flavorless vapor. At first that's all I ever got, though I am getting the hang of things and hitting the flavor sweet spot more often. A very slight difference in draw can be the difference between zilch and flavor strong enough to leave you wondering if a drop of pure juice landed in your mouth (even though it didn't).
I came from smoking a pipe, which means long slow steady draws. Vaping seems to call for shorter pulls (don't need to keep the tobacco burning) at even lower (though not too low) airflows with my gear.
Keep trying, and when you find the zone just try to stay in it. That's what I'm working on.
