So no steam etc @ 122C I'd say the gauge is giving a false reading some how.
wait till you have a proper gauge fitted and see if that makes a difference.
As I mentioned 122c would have steam hissing out even blowing a hose it
would have that much pressure
Making sure the ohm on the sender match the ohm of the gauge
Id be checking the settings on the Scan-Gauge
Did you notice where the OE needle was sitting??
