I think it would be best to give a link to the log as well so it's easier to see the actual numbers. I see that you are here in Cali as well and the gas here seems to be crap, we don't get 93 and it doesn't even seem to be high quality 91 either.
I'm running a stratified tune as well, and just recently had it re-done for the FMIC I put on and am waiting for the OAR to set in before doing some logging. But I still see negative corrections and have a feeling it's due to the gas here.
