For sale BMS Power Box (PBX) for N52 Non Turbo engine
Never installed it on my 09 328i. Brand spankin new. Bought it from Bavarian Motorsport for $279+tax. Selling it for $200 delivered. The BMS Power Box is a piggyback-style performance tuner for the BMW 2.5L & 3.0L N51/N52/N53 6-cylinder motors. It features easy installation and removal, the ability to switch between seven user-selected performance maps, throttle remapping for snappier response (elimination of "throttle lag"), and dyno gains of up to 10 hp and 10 ft-lb of torque. (The power gains are even greater when you make other performance modifications such as a cold-air intake and free-flow exhaust.) The Power Box can be turned on or off from inside the car. And fuel economy does not change during normal driving. Installation does not require any cutting or splicing but does require removal of the factory engine control unit harness plug. Some factory wires are removed from the plug and replaced with or connected to wires from the BMS power box. Completed installation is very discrete and is not traceable.
