Okay I just got a vapor flask classic a few days ago. I put my tfv8 on it with a quad coil at .15 and it's only letting me go up to 106.3 watts. If I un screw the tank I can turn it all the way up to 150 but as soon as I put it back on it automatically drops it back to 106.3. If I unscrew it and play with it a little and get it to read as a little higher resistance it lets the wattage go higher. Does it maybe have some kind of safety feature or something or is it just messed up?
