logs looks pretty good. Im assuming u have a 2008+ here. If so, boost is right on point. your first log is a bit short. in the future, make log more like ur second log. Ideally around 2500 rpm to redline and WOT.

Log looks good. You may want to get a more extended run (start at a lower RPM, but above 2000 RPM) for future runs.

Im not Cobb tuning, but i can say that you may have experienced knock during this run. It was as soon as u went WOT throttle which is strange. Your dam is 1, which is great and your boost is spot on.
Continue to drive and post another log, hopefully that knock will have gone away.

actually... this is not strange... its typical. as you go wot it is typical to get a single knock event, and this is what this is. then the ecu straightens things out and all is well...

I personally would not want it to do this, so if everytime you go wot you see this you may want to flash "down" a map.

Log looks good. The single count of feedback knock correction is normal noise. It is typical to see that type of correction during large throttle transients (and even sometimes less severe transients). It may not happen every time, but when it does, it is not generally a concern.

I would go ahead and get a few more logs - doesn't hurt and always a good idea to get multiple logs to make sure there isn't any intermittent knock or other issues.

Good practice to check your A/F Learning 1 A,B,C,D fuel trims every once in a while over time. They should be within around +/- 5%. If you start seeing any values outside of +/- 8% or so, you might have a fueling issue. New turbo Subarus have been having issues with some intake tract leaks from the factory.

Keep driving on it and see where your fuel trims end up over time. Your load is a bit high for a stage 1 2008 WRX, which makes me think you may have a boost leak. Let's see where your A/F Learning 1 A,B,C,D values end up.

Looks good. I would just keep an eye on the A/F Learning 1 A,B,C,D over time (say every once in a while through a couple of tanks of gas). You can view each of these via live data. They should generally be within +/- 5%.
