Just to add to this, I got a DNA250C device a week ago and it was working great. I flashed the Guages theme to the device, then fitted a new build and kept intermittently having the device drop out displaying "throttling". So I rebuilt the same coils again ensuring everything was good, then again after a while the same throttling message appeared. Stumped I put back the other atty with the build I was using all week and the same thing happened. Flashed back the default theme and I've no issues since even with the same atty and build that was throwing the "throttling" message with the guages theme.
