Drivetrain Overboost problem

Overboost problem
Would a slipping belt cause an overboost (high manifold pressure) condition?
I figured if I am going from say WOT 15psi, slip down to 5 (or less), and spike back to 15~16Psi if that rapid change in pressure could cause an intermittent overboost condition? car has a 17%
Also what type of sensor is triggering the code (pressure, hall effect, etc)

The T-MAP sensor in the MCS is a 2.5 bar sensor, which is linear up to 22.05 PSIg. The ECU is highly sensitive to the MAP sensor clipping and will immediately post a CEL along with the corresponding P0108 code. A slipping blower belt will not cause this situation, and if any supercharger setup is, there is a restriction worse than stock present. A single-turbo conversion upon crossing the boost threshold with a loosely damped boost controller will easily cause this, however!
