The Wotofo braided wire can be used to make a .24 ohms single coil at 5 wraps, 3mm inner diameter. Since the vapor production you've been getting is not enough for you, you could also decide to make it 6 wraps and/or increase the inner diameter to 3.5mm, assuming the build deck of your RTA has enough space for making it fit. Doing this will bring the resistance up higher, but not terribly so. For example, at 6 wraps and using 3mm inner diameter, a single coil made from this wire should still end up below .3 ohms. Don't forget to work out the hotspots before the first use. (I'm assuming you already know how to do this, but don't be afraid to ask if you don't.)
Also, if neither your Smok mod nor the batteries that you use in it appear to be getting more than just a little bit warm, I wouldn't worry too much about the inconsistencies/inaccuracies as for the numbers being displayed by the mod so just experiment with the wattage upping it one small step at a time till you find that sweet spot, take it a step back if necessary. If it works, it works, for as long as it works.
