Huffing that much boost under those conditions likely blew out a seal/gasket somewhere in the intake tract.
Motor/parts heat up and things move around.
Info please!
What is boost?
Boost is the 'backup' of average blower pressure in the intake tract trying to get into the motor.
If there is a leak, the average goes down.
