I use 26g 3mm contact coil 8 wraps for about .6 ohms.
I also place mine fairly close to the air inlet.
Also make sure your coil legs are actually under the screws. 26g tends to slide over beside the screws, and though it holds fairly tight, it isn't an ideal connection and can cause issues at higher power levels.
Play with the wicking. In the Intake, wicking can mute the flavor. It'll seem fine, but a slight change can make a difference.
