Since when is 12.xx slow? My slow 13.074 was hard to get and I've learned how little it takes to go slower and how perfect things have to be to go faster. You haven't gotten a faster time because the transmission is shifting early from 1-2 and 2-3. The question is why. The AFR looks good except it's a little rich at the top. The timing looks good too. I think the tune is real close to optimal. It must be associated with the code the computer is throwing. Figure that out and let us know. I'm headed to the track as soon as the rain stops. I don't have high hopes for a good time, but only because the tires can't hold the horsepower! I'll be playing with tire pressures and going real low if necessary, in hopes of traction.
