If you remote start while looking at the front of the truck, you can see the DRS open and close during its self test. Also aids in warming/cooling down engine.
I just had mine come on yesterday. 24 Raptor.
Came on after using 4A for the first time the day before.
It was also after plugging in my Procal tool screen to mess around with what readings I could display on it. Not sure if that was related.
Procal tool was saying the code is P160A

I’m curious if there would be any HP increase with the tune already installed. More air can’t hurt. I looked on the bronco forum for any dynos with the combo installed but didn’t see anything.
