I regularly vape TC using DNA mods, mods flashed with Arctic Fox firmware and a few other misc mods. Also vape wattage mode on about 1/2 my current rotation.
Red Panda and Arctic Fox firmware, both developed by the NFE Team, bring compatible mods TC up to "nearly" the performance of a DNA or YiHi mod.

I am really curious --- have you asked your question in the NFE forum? If so what did they say? I have a pretty good idea of what a few folks there
would say.
How many changes did you make within NFE Tools and then upload to your various mods?
With TC I do not lock the resistance on any of my mods. You do not need to on a DNA mod for example. In fact it is recommended by Evolv that you do not. From my experience you don't need to on a mod flashed with Red Panda or Arctic Fox.
I usually have mine set to between 375°F and 420°F --- AND --- I have never gone higher than 440°F. There is no need to IMHO.
I vape MTL to DL anywhere between 12w to 40w. My coils are usually between 0.3Ω and 0.7Ω. I run ss316L simple round to claptons with TC.
No one that I know vapes anywhere near 580°F. Zero, zip, zilch, nada. There is no valid reason -
that I know of - to run that high in TC mode.
Don't take this the wrong way but my initial reaction was --- what the chuck. Reckon my facial expression looked like so,

.
Looked up vaping the 'alternative' stuff and even those don't require anything over 410°F (356°F to 374°F seems to be the norm).
For crying out loud, 580°F is higher than an oven set to broil!!! Oven broiling temps are around 550°F. No one needs to broil their juice.
I'm with Izan and zoiDman on this.
We need much more info. Until then good luck friend.
