Unfortunately, most performance-enhancing methods (tuning) for BMW diesel engines work by simply increasing injection pressure to dangerous levels. This puts a lot of stress on the whole injection system and results in higher pressure on the BMW engine during combustion.
Over time this this method will wear out your injectors, pump, and high-pressure fuel lines of your BMW BMW X3 G01 and X4 G02 diesel engine. It will possibly do permanent damage to your pistons!
Our Engine Performance Tuning Module for the BMW X3 G01 and X4 G02 diesel cars is totally different and does not increase any injection pressure at all!
The dAHLer Engine Performance Tuning Module simply lengthens the injection time by a small amount which results in more power and torque but stays within the BMW engine’s safety regulations.
