Chirping from air governor

Hello all, I’ve recently replaced my dryer and air governor and everytime the dryer purges air there’s a chirping sound coming from the air governor. When I back off of the set screw from the governor the chirping goes away. Parked or driving the pressure slowly drops to around 100 the chirping goes away and starts to build air again. I’ve noticed the chirping will go away immediately if I disconnect the line that runs from the governor to the dryer. Not sure if it’s back feeding air and slowly releasing pressure that way or not are there any thoughts why this could be happening?

 

Fair enough today’s my first day running it like this so I’ll keep on trucking. Thank you.

 

Fixed. The 3-4 inch hose in the Air Inlet Port had a small rip on it. ‍♂️
