Benefits of higher performance underdrive pulley

like everyone else, I am always looking for that next performance upgrade for my 1999 986 Boxster: have already done L&N IMS retrofit, FVD performance software, K&N air filter, FabSpeed Sport Headers, Fabspeed MaxFlo Exhaust system, replaced OEM cable throttle body with 1999 996 74mm cable throttle body so I could install 996 IPD Plenum, put Victor Rims and Yokohama tires on it, adding NT Auto rear wing and diffuser, drives great and sounds even better.......... pardon my ignorance, will replacing the OEM underdrive pulley with higher performance system add HP and/or torque, if so, is there consensus on which manufacturer is best?
