If you are running that rich under WOT, I would have it checked for leaks, the tune might be fine.
Plug in your Accessport, and under the Live Data section, what does A/F Correction A, B, C, and D say? What does the Dynamic Advance Multiplier say?
Could you take a log with the Accessport and post it up?
I saw another post where you said Ptuning did the tune...did you mean Precision Tuning in Lakewood, NJ or Ptuning in Virginia?
