DiabloSport AFM S1000

Just got this in, and I plugged into my car, but how do I know this is truly working?

It has a constant red light. Car does feel like it got a little boost, no more delay. But, how do I know it isn’t me just assuming the DS is working?

should go into AFM and stay in AFM more than it did previously.
if unsure, may need to remove it and take note of when/.where it comes n then compare that to the behavior with the device installed.
