These are the numbers I have been using now and they seem to be the best for me so far. I don't actually look at the temp as it goes, but I base off of the resulting abv. With other numbers I was getting hot spots, especially around the outside of the load. With these numbers I get incredibly even abv (as long as I rotate the stem). I am actually amazed how changing to these numbers has really evened out the colour of the load. What does the boost number do? The problem that you describe sounds the same as what happened to me when I first got my cuboid/eraser combination. I would set it to TC but then as soon as I pressed the fire button it put me in power mode. The problem for me was in the atomizer in that the two wires were touching pretty close to the base. Once I fixed that, I haven't had the problem since then. At least I think that is what fixed it considering your problem is with multiple atomizers.
