How long should a vacuum box on the Turbo itself hold the vacuum

How long should a vacuum box on the Turbo itself hold the vacuum?

I get code 30FF and 30B1 on the dynamometer and an engine emergency run.

Have already done vacuum diversions, crankcase ventilation, new vaccum solenoid

Assuming you mean the wastegate actuator, it should never leak down or lose vacuum. If it does, it's diaphram is ruptered and needs to be replaced
