Default Hydra 5700RPM hesitation, cannot tune out

I have an intermittent hesitation around 5700-5800RPM that I cannot tune out. It happens about 50% of the time.

It "feels like" a misfire.

AFRs are steady at 11:1

Nothing at all shows as far as high knock voltage.

I have tried lowering boost to 13psi.

I have tried lowering timing there to as low as 15, incrementally.

Anyone have a clue?
