Well, I went out and logged, and the problem is no longer there. Worst number was a 117.5. This got me to thinking about why it's not doing it now, and I remembered that my old ecm died on me due to unknown reasons, and this problem was showing up when I was using it, so there's a good chance that it was on its way out when I logged the problem. I just had completely forgotten about having to put in a new ecm. On that thought, is upgrading to the 7427 worth it in your opinion?

The only question I have left is how much should I smooth out the fueling table? Do you have a picture of what your tuned fueling table looks like, or could you post a bin that you've smoothed out the fueling on so I can check it out myself?
