Your boost safety set to 18 psi and you are hitting 18 psi and kicking you to map 4, you are over boosting which you need to see why.

You may for now raise your boost safety to 19 psi or 20

Hey,

Welcome!

Your overboosting- raise your boost safety up to 20, and save.

While you are in that menu, also, enable your 6cyl logging too.

You can also, manually lower your FF setting to 70-80.

Raise boost safety to 20 psi.

Lower FF to 80 and get another log on map 5.

What fuel are you on?

Enable 6 cylinder timing.

You access those via your user adjustments - you need either a laptop or a tablet

Last log looks okay- a few timing corrections, but that’s likely due to 91 octane

Still need to raise your boost safety
