Found some leaks in my intake...(reference pictures added)
Did my first pressure test today and found a few minor ones. Used the first thing I could find that would bubble but was mild...Murphy's oil soap.
New at posting multiple pics so bear with me.

The leakdown takes a considerable amount of time so I don't think I'm losing much boost. When I cover the PCV with my thumb and put the oil cap on, it held pressure steady. I was afraid of pushing oil somewhere where it shouldn't be so didn't cover the PCV w/more than a few psi.
I checked all hoses from the top of the ICs to the throttle body. Even sprayed the face of the ICs in case road debris punctured the tubes, all was OK (except for the leaks pictured). Couldn't really get at the tank/core interface but based on the slow leakdown, I don't think I'll pursue it any further.
Next steps I was considering:
Reset the ECU and observe boost.
Find a nice person w/vag in the south jersey/philly area (hint, hint) to help check req/actual boost and MAF values.
Any other suggestions or comments are welcome!
Bonus w/ the Murphy's, my engine bay received a nice detailing and smells like my dining room ;-)<ul><li><a href="https://forums.audiworld.com/s4/msgs/1460328.phtml">yesterday's post</a></li></ul>

It definitely looks like it in those super high res pics. Seriously though, it does look like to me
it is beyond the hose connection and, thus, would have to be another leak in the bip. that sucks.
