Hemi tick?

so I noticed this annoyng racket coming from the engine while I'm driving near a wall, other cars or a divider. It gets louder when MDS is on and becomes faint again when all cylinders fire up. i tried parking and revving the motor up but heard absolutely nothing at all. Is this the infamous Hemi tick?

Mine is noisy too. Since new. I recently switched to mobile 1 full synthetic but no change. I'd like to disable the 4cyl mode and will after I get the programmer. I can't imagine it's good for the engine especially since fuel is a lube on the upper rings. I have checked mpg resetting it while in 4cyl mode, can't see that it helps at all.

I hope the programmer will let me disable it.

Thought about just getting a cat back exhaust but those are high, drown out the noise lol
