it does helps with reducing popping, because it enriches the air/fuel mixture. however, in my opinion, taking the O2 sensor out, helps as well, because the bike in not switching back and forth between the open to close loop. Booster plug does not work in the closed loop, only in the open loop. Theoretically, upon deceleration, the ECU enters the open loop, but that transition is not always smooth and can be jarring. blocking the Pair Valve also helps with popping because the air is not injected into the exhaust.
