E46 320d / E39 520d Performance chip (M47D20 / M47TUD20) 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.
