Ok, sounds to me like you have the Tron tank. Make sure your machine is sen in Ti mode for that coil. If it is temping out, it thinks the coil is dry for some reason. You might have a bad coil. Switch to a different one, or go to one of the Kanthal coils and use VW mode. You might also be using a juice too thick to wick fast enough to keep up. Try turning the power down or using a thinner juice.
