Closed loop boost control allows the engine management (aka aftermarket computer) to control the boost more efficiently. It allows the boost control valve to operate the wastegate more aggressively initially, and then it tapers off towards the end of the boost by how much you want it to taper off. Open loop boost control would be with a manual boost controller where you set the manual boost control valve to open the wastegate at the PSI that you determine.
