The safety your are throwing is "1" for overboost.

The log files you have uploaded are massive, and frankly hard to read, because they are full of not needed data.

Proper logs to help diagnose issues are generally done in 3rd gear, WOT, traction control fully off.

Turn on 6cyl timing.
Set your duty bias to 50 across the board.
Relog.
What fuel are you using?
What plugs are you using and how old are they?

timing doesn't look great.

we can help the boost curve w. some duty bias tuning, but the stock turbo isn't the most efficient.

Bump your FOL up to 80

And let’s add 1 gallon of e85 to your current gas tank (unless you are on empty)

Drive around for a few minutes after adding the gallon (let fuel mix)

Then re log, let’s see if that cleans up the timing a bit

Could it be an issue with lpfp? I tried to log this morning with fol at 90 (attached) but went into limp mode. The error codes are 2efe, 2f02, 2ee0, 2eed.
