Still baffled at your log as a whole

Why is your WGDC not 95 during spool? Why is your PID P 0 during spool?

I have no idea...

Yet another log. This one's real wonky. WGDC and P seem slightly more normal though. Throttle Plate Angle is 100% the entire time. No misfires.

Those turbos are done, or your wastegates are totally screwed.

Why would that make it request that ridiculous AFR?

EGT activity as well.

Also, get a wideband.

I have a wideband. I just didnt log it simultaneously

It is NOT a hardware issue.

Here's a log I just took with a different tune that does not have such an issue.

No clue, but you'll have to compare map by map if you have a tune that works and one that doesn't.

95% sure I found the issue. My one EGT sensor is broke. I disabled the EGT DTCs but didnt max out TABGSS and TABGSS2. I'll report back.

That does not look like a damaged EGT to me.

Before I disabled the DTCs I was getting EGT intermittent codes and the logs the EGTs randomly jump from 900c to 1100c in one step and back down a couple steps later.

Disabling EGT's is done by 3 codewords, not disabling DTC's. That does absolutely nothing to solve the issue.

Maxing TABGGS and TABGGS2 fixed the issue I believe
