Well, how did you break in the coils on the fixed wattage mod you had? I would/will say, start with some long inhales at NO wattage (don't hit the power button) and increase by 2 watt increments (continue priming, the idea is to use suction to start capillary action where your coil slowly gets eliquid inside and it breaks in. One logical place to stop (other than where it's vaping well would be at 60 watts ONLY every device is different. Depending on a variety of factors your smok stick may SAY it is a 60 watt fixed output that doesn't necessarily mean it IS that, though. Also, I have some mods that just convert power more efficiently than others, I have no idea why, other than it's the board.
If your coil is burnt/ruined, toss it, toss the juice, disassemble and wash the tank (and yes the O rings too). That's the only way you will find out what "works" with the Alien.
Best of luck,
