Lean code under WOT? Correct me if I'm wrong, but a lean code gets thrown when the sum of Short Term Fuel Trim and Long Term Fuel Trim is greater than +30% under closed loop conditions (i.e. reached the limit of adding fuel trim to what it thinks is a lean running engine).
What are your Low and High Throttle points set to (as a % of TPS)? Know anyone with a good OBD-II scanner that can pull the freeze frame? (Alex's software does, under the "Freeze" tab. Grab that before you clear the code if you can.) That way, you'll know exactly what was happening when the code was thrown (MAF, TPS, ST and LT Fuel Trim, O2 values, RPM, MPH, ECT, SPKADV, etc.).
We both need to get to a dyno for two reasons: We were running neck and neck on hp last time we dyno'ed and have done significant mods since then, and we both need to get our A/F tuned. I'll take it on ft-lbs and you'll take it on driver skill. Pretty heavy compliment to your work if you're in a hp arms race with a guy that has 500cc more on otherwise the same basic engine configuration.
