may be the injectors maxing out... do you know what the pulse width was?
I just recently observed a local club members car run dangeriously lean on a dyno... I believe he solved his problem by replacing the fuel filter, it was clogged and at WOT he wasn't getting enough fuel delivered
If you can get the injector pulse widths though it'd help
