The TC kicking in is simply throttling the wattage back to keep the coil at your desired TC setting. It's still producing vapour, it's just not producing the same amount or as hot a vapour compared to the same wattage without TC. But, it doesn't sound like all is working as it should be here!!
The long format 0.0006 number looks like a TCR number (I don't know what your mod is and you've supplied no mention of what you've done to get this number, but it certainly sounds like an absolute TCR). You DON'T want to be messing around in the TCR M1, M2, or M3 modes. Simply put the mod into TC Ni mode, then reduce the wattage and TC back down and start again, gradually walking them up again. Hopefully you'll start to get a better vape. Hang in there, we'll get you there

It sounds like you've accidentally entered one of the custom TCR modes with an incorrect TCR for Nickel, which could give an underwhelming vape. Putting the mod into the correct mode for your Nickel coils should rectify the issue OK

Let us know if that improves things
. Supply some info on what mod you're using too and how you're getting to the long format number, just to be sure it's an accidental user error and not an issue with the mod itself too bud
