Easy way to add some extra power to the N54 engine without all the faf. I don't have the instructions anymore but they are easily available on line. Made a noticeable difference at the default setting of +3 psi—adding an average of 30 horsepower and 40 lb-ft of torque to the wheels and can be turned up further.
