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 3 series sedan G20 or 3 series Touring G21 diesel engine. It will possibly do permanent damage to your pistons!
Our Engine Performance Tuning Module for the BMW 3 series sedan G20 or 3 series Touring G21 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.
Our latest technology also controls boost pressure to unleash a wave of torque at low rpm which will push you into the seat.
