Rather than play 20 questions about all the important variables you don't include in your post, I'll go with just the things you do include.
Your problem is likely to be coil surface area... or lack of it. As resistance goes down, one must increase wire thickness, or increase the number of coils in parallel, to offset the loss of wrap count/surface area.
At an estimated 3 wraps, you don't have much surface area, so you're not really gaining anything over a 0.4Ω set-up using the same wire gauge but double the wrap count.
All else equal, save for the doubled surface area and current draw... the 0.4Ω set-up might actually produce more vapor.
If you must run at 0.2Ω, switch to a thicker wire, and the resultant greater number of wraps/surface area... or run four 0.8Ω coils in parallel, or take the 28 you have, and using 2-4 strands, twist it. In all cases, more surface area for a given resistance = more heating surface to atomize juice.
See my first sig line hyperlink... use the modeling calculator to build coils, including twist coils, "wrap optimized" for the resistance. I personally use the 7-11 wrap count optimization... no less than 7, no more than 11. It's somewhat arbitrary, but, if it doesn't fit in that range with my target resistance, I change wire gauge until it does.
