Clicking noise
 

So I have seen many forms on ticking noises and none of them seem to relate to mine. I have a 2015 Silverado 1500 with the 5.3. I have leveled it, volant CAI, Jet Throttle Body, and a Blackbear tune.
Here is my issue: there is a ticking noises in the front driverside area that that seems to be right behind the break pedal area in the engine bay. The weird thing about this noise is that it correlates with the rpms of the engine. So the higher the rpms, the more ticking. But, I can't hear anything with it in park just idling. Any thoughts?
