Ok, mystery solved. There were two problems, both caused by me: The first was the cold air intake, where it connects to the turbo/engine was loose letting in more air than necessary and thus was throwing a lean code. The second was that after doing the spark plug change, I did not re-clip the high-pressure fuel pump sensor and it was loose thus throwing a fuel system code. The dealer removed the cold air intake and reinstalled the factory air intake and "fully seated" the fuel pump connector. The car is back to normal. I got to pay the dealer what I call a "stupidity fee" for them diagnose and correct these issues. I appreciate everyone's thoughts in this thread!
Glad it’s sorted mate! And you’re not missing on power with the stock intake. Just noise. Don’t be shy with the JB+ or 4, great products that boost power.

Hey man we've all paid the stupidity fee at several points in our auto journey I'm sure. I know I have!
