Boost creep happens when the turbo builds boost too fast and cannot expel the access Pressure fast enough making the car run at a higher boost pressure. Why is this bad? Boost creep can cause Ringland failure due to the car creating pressures the manufacturer did not design the motor to handle. You can prevent damage by installing an external waste gate (EWG) and an electronic boost controller (EBC). This will allow the car to exert the extra boost at the proper ratio to accurately run the car at the programmed boost setting.
