aFe Scorcher GT plug-and-play module for 2009–2011 BMW 550i/650i/750i with the 4.4L twin-turbo N63. A 30-minute install delivers substantial measured gains in testing—verified increases around +40 horsepower and up to +60 lb-ft of torque—by adjusting boost-related signals. The kit includes a quality case, factory-style connectors and an LED switch for four in-cabin power settings. This version accommodates the early-style sensor 1 TMAP connector used on pre-mid-2011 vehicles.
