E60 535d / E90 335d Performance chip (M57D30TU2) 03 - 08

 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.
• For example ECUs with bosch nr: 0281015241 , 0281013854 , 0281016640 , 0281014287 , 0281011762 , 0281014206 , 0281015128 , 0281013852 , 0281012191 , 0281014545
