Very nice (WOT)!

Monitor your "A/F Learning 1": it should be +/-5%, some say +/- 8%.

Make long log of regular driving.
If "A/F Learning 1" is lower than -8% (too rich) than you have to clean your MAF and air filter, check for boost leak, then adjust your tune.

Your log looks pretty good. Nothing obscure to me.

Future reference, logs in 3rd gear are your best option.

Also, the whole 8% vs 5%, typically Sti's can reach up to 8% with no concerns and regular wrx's are the 5%. I believe i read that not too long ago.

Logs look good. The A/F Learning has some borderline extreme values - something I would keep an eye on over time. There have been reports of intake tract leaks on brand-new Subarus from the factory. If it gets much worse than -7% (i.e. -8%, -9% etc.), then it would be something to check out.

Reflashing the car also clears the fuel trims, so the fact that they are low now does not tell you anything. They can take time to populate accurately. Since you were approaching -9% before and given this is a very new car, you most likely have a boost leak. Apparently, Subaru has been having problems with this from the factory lately. From what I've read from other reporting the issue, it may be the throttle body to intercooler coupler. But, I would consider getting a pressure/smoke test of the intake tract done to find any leaks. The dealership isn't going to care about this unless there's something obvious (like a check engine light or a noticeable noise), so you may be on your own for diagnosis.

You'll be fine, just drive conservatively and do not do any heavy throttle runs.

Did you reset the ECU (via troubleshooting menu on AP) or disconnect the car's battery after fixing the leaks?

If you did a reflash (and not a realtime flash) or a reset, then the trims should have started at zero and then started moving at some point once you began driving.

Just keep monitoring it and see where it goes over time (through at least a tank of gas or so). Those values are borderline at this point.

Just an update I decided that the best thing for my car would be a protune seeing that the a/f was not looking good. I brought it over to rob at AMR performance and now I couldn't be happier thanks bill for your help
