What sort of timing are u PFC guys with RB25DET's running?

at 12.5 A/F full load at 5500rpm+ at 1bar on a GT3040 im finding myself needing to run 24 degrees of timing, doesnt that sound a touch high? my knock isnt even 1/6 of the knock gauge,

Any less timing and it seems to almost have like a power surge and loss problem.
