Extreme overshooting of the hotend

[Jason Freeman]

I'm having issues of extreme overshooting of temps with my Dyze End X hotend. I've tried PID tuning multiple times. I've inserted the values into the firmware but still getting the issue. I set nozzle to 250C (ASA) and it will randomly shoot up into the 400-500C range during the print. What could be the cause for this. It's running on a BTT SKR Mini E3 V3 with a BTT TFT35 display (I believe).
