E46 330d / E39 530d Performance chip (M57D30) 98 - 04

 Tuning Chip optimized for higher power output and lower fuel consumption.

• The torquelimiters is rised and fuelinjection is optimized against higher level of boost. By using the extra energy at lower/mid revs, the fuelconsumption gets lower. Also a lot of other maps is tuned for better performance.
• An optimized chip makes the torque rise earlier in rpm and the engine becomes more rapid.
• Ex ECU 0281010314 , 0281001830
