Were you monitoring EGTs?
AFR 11.8 full load WOT, Cruise 14.0-14.5, light throttle light acceleration 13.5-14.0.
Only was I can monitor EGT's is by the colour of the manifold/turbo, it wasnt glowing so they were not too high is all I can say.
It looks like my head gasket was not sealing correctly from what Karl has said!
