You did read what you quoted right? I can't go higher. At 40watts I am not coming close to the temp I have set. At 450F at 40watts I'm hovering around 400-420F. At 480F I still hovering around the same temp which isn't changing the vape.
I can't get the warm vape I enjoy using these coils on the DNA40 like I have been on the SX Mini. With the Kanger coils this isn't happening.
Hm, that's weird. You can easily overpower Atlantis coils in my experience. Might be something else going on. There might be a clue that you are getting such a heavy drop at refinement. What mod is this? Maybe the 510 or the ground is funky.
