In general terms (i.e. without disclosing proprietary info) can you talk about what tuning you did for other-than-WOT conditions? I mean I know basic tuning is air:fuel ratio and timing adjustments. Anything else?

Additionally, I agree with the theory that stock tuning doesn't maximize power for emissions reasons. I think there are 2 specific reasons: 1) minimize emissions and 2) protect the catalytic converters from accelerated deterioration. I wonder if there's any more to that story...
