Help - new FI HFC leaking at gaskets on exhaust side

I believe I am battling a similar issue - could you hear the leaks in the cabin while revving? Say like above 4k?

Unless you have a huge gash in your exhaust, I doubt so. Just look at your flanges while in neutral and have someone press the accelerator.

Spent Saturday taking it all apart, cleaned flanges with a Dremel wire wheel, and permatex'd the sh*t out of everything. Took a reading today after running errands (pic below).

Now we wait.

After driving today. A permanent code was still stored in the ecu for run lean condition, and that has since disappeared (something i learned: you can't erase permanent codes, only your ecu can determine if the issue is resolved)

permatex=poop in my experience, my berks where also leaking with permatex until I got some damn legit gaskets... no more leaks or codes 7k

Yea Dave I've got both gaskets and the permatex on there. Hoping the permatex will help seal up imperfections.
