Does Lycoming make any sense?

I was wondering if the excessive fuel flow indication changes with pump on
vs off.

Robert, does it matter whether the boost pump is on or not?

No, pressure holds solid at 22lbs.

Your turbine JPI device may only report to the JPI display.
The fuel pressure indicator/fuel flow that was original
equipment shows high pressure is there is a blockage and low
fuel flow. But the higher indicated pressure is also
interpreted as a higher fuel flow.

If you have EGT on each cylinder, checking temperatures and
thus fuel being burned can help determine if the cylinders
are rich or lean.
