Hmmm AB works with MPT until I set the core boost to 2035. Then it goes wacky again. It seems like setting 1960 in MPT stabilizes it until 2030 boost at least so far for me. I'm newish to this, maybe there is something I don't understand. 5700 non XT. I'll try it with more power, idk if the sensors go wacky or if it's actually hitting these cores.
