Spark plugs or coil packs causing misfires is my guess. Rail pressure looks fine in this log which is usually the main culprit. I don't see that you went WOT though. You only hit 71% pedal. Did the car "shutter" (misfire) in this log?

Replaced coil in cylinder 2 and it fixed it. Thanks. New logs https://datazap.me/u/b335t/replaced-...18-28-29-30-31

Cyl. 4 still has +5 timing corrections near your 4th gear shift.

Knock vs. Pre-knock correction argument here.

Looks like you're on stock(ish) map with max 10psi being pulled here?

Make sure to run your logs with DTC and Traction off if applicable. The throttlebody blade likes to close and limit boost if not, which feels like a stutter sometimes.

If it feels fine I wouldn't sweat it though unless it rears it's head.
