Dual POP Charger Only Useful if the TT engine is producing 450 or more HP. The kit consists of TWO POP chargers installed side by side where the air intake was. The MAS will be relocated on one of the side, while the other will only have a tube. (If the car already has a POP charger, only the required parts will be needed) Because the MAS will only see HALF of the air going to the engine, the ECU will have to get a new EPROM programmed to handle the change. The low speed driveability may suffer, and the JWT "low speed driveability update" should be installed (comes free with the DUAL POP charger). Installation of the "low speed driveability update" will required to cut some vacuum lines, drill a hole in the right stock surge valve, and route a hose to it. Henri Le Hir
