When I did a search lots of things pointed to it being a vacuum leak. When I first checked I found that the stock y-pipe was used after getting the 82mm TB put on. I thought it was that, so I fixed that. Checked for leaks, did a bunch of things and nothing. At the end it was indeed a tuning issue. I honestly didn't think that was the issue but when I used BIP it all went away. I never got a CEL...
No problem hope it all works out quickly.
