I edited my post since you quoted me. Mind you this is looking a minor single incident FLKC which iirc subaru even considers "okay" but some tuners consider more on the aggressive side. It is not enough to pull the IAM for being considered major knock. Your AFR's honestly aren't that much richer than a lot of others, may just need to pull some of the upper voltage area down by a small percentage. I prefer turning of fuel trims for tweaking the maf and then re-enabling. They can swing up and down here and there and getting them to land consistently close to 0 is a bit of a task which is why its a good idea to keep on the conservative side of tuning with the LTFT enabled for WOT.
