What is this component on a TSIO-360-FB? "Turbo Pressure Relief Valve"

Hello friends,

I was looking at images of the TSIO-360 on this Engine and comparing to our engine, noticed it does not have this component. After some Googling, it appears as a Turbo Pressure Relief Valve. Is this the infamous Fixed Wastegate? Just trying to get to know this engine better, it was overhauled in 2018.

    The Turbo Pressure Relief Valve is a normally closed valve in the turbo boosted upper deck pressure plenum. If the upper deck pressure gets too high (above a set value like 43 inches of Hg), this valve opens to the ambient air which reduces the upper deck pressure. Consider it a relief valve that prevents unusual and abnormally high upper deck pressure.
