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?
