Please explain what you mean by this statement. As far as engine performance, there is nothing different about the N54 engine between a 335is and a 335i except that BMW has increased the boost slightly to produce an additional 20 HP, plus the additional 7 second torque boost, all done with the ECU. It is the same physical engine, the only difference is in the ECU.

P.S. on our 335is the letters are in lower case.
