Default Oily black sludge

Hi all,
Wondering if anyone has had this issue or knows what is causing this symptom.
The other day as I was doing the oil change I noticed that, what I believe is, the intercooler pressure hose on the passenger's side had some black oily sludge on it. I wiped pretty clean, reached up as far as I could.
A few days and miles later, I checked it again and I now see a thin coat of an oil substance coming from the top side closest to the intercooler. The drivers side is dry and clean as a whistle!
Does anyone know what this is relating to? I plan on investigating further in a few weeks once I get under there to do the spark plugs and coils.

This is on a 2014 Turbo S with a GIAC tune and an Armytrix exhaust.

My buddy found this on his 14' several weeks ago, was going in for service so he had them look at it, the dealership claimed it was from his giac tune that caused extra boost and that caused the issue, "making the pipe weep oil as that called it", of course that was total BS, he ordered a new pipe, believe it was 69 dollars, that had dual seals on it, looks like an updated design, but upon removing the leaking pipe it appeared the seal was MISSING, this caused the issue, but since he had the new pipe he replaced it and end of problem. Not sure if that's your issue but sure looks the same

Ah thank you for the info! I will take a look soon before buying the pipe, maybe I just need to adjust it or check for the missing seal.

Also, if it's not too much to ask, just in case, do you know the part # your friend ordered?
Is it 991-110-626-71 and maybe 999-512-349-01 for the clamp, if needed?

Are you referring to this? My driver side also doesn't have it.

Yes, same thing, this is how mine was at first. I cleaned it and checked on it a few drives later to make sure where the leak was coming from.

I will try to investigate soon, once the weather here in NY permits, while I do the spark plugs and coils. Hopefully it is what hcvone said - just the pipe or pipe fittings/seals. The pipe itself is $68+$3 for the clamp on the other end and shipping from OEM Exotic Auto, so its not a bad fix.

What year is yours? And what exhaust/tune/mods do you have?

2014 w/ Boost Logic Titanium Exhaust and no cats. I'm using a tune provided by Sam but I doubt it is a tune issue.
