The latest 3.0d engine from BMW, the N57D30, runs the latest generation BOSCH EDC17 ECU controller with tuner protection and no OBD flash capability. The 245bhp engine is a superb base for tuning and in our hands is capable of producing 335bhp and a massive 475lbft torque. The power is so impressive it eclipses the N57D30T1 3.0 Twin turbo engine which produces 460lbft standard.
The good news for the E93 325d owners with 201bhp is that it is simply a factory detuned variant of the 245bhp, making 335bhp and 475lbft available to those who want it. Likewise, we are also to provide a more subtle power increase for those who don't want M3 destroying power.
