Another great tech post...thanks ksfrogman, I found these very interesting to read. We need to start a compilation and sticky these tech bits.
As a 325i owner and after having read this post its quite disheartening to hear the lengths BMW went to detune/compromise this engine's output. I definitely feel shortchanged
I just wish we had the high output N52B25 rather than the low output N52B30 in our cars. At least the 2.5 is at the top of its game
