So i've been liaising with an Ijoy Rep and discussing about the TC, I told them the temperature on TC is very high. Not sure if they can do anything about it. Time will tell if they will put a fix on the next firmware.
So far still tuning I got it set for TCR 60 and lowered the temp to 390F which feels about 430F. This mod is ok, I paid cheaper than my wismec rx gen3 dual. For wattage only this thing rocks and it's super fast ramp up, minimal lag on firing. Very smooth vape for wattage only. But that's not what I bought it for, I got it mainly for TC. Still tuning I will report back if I change anything.
