ZPOST - View Single Post - N52 performance gains 3.0i vs 3.0si is it just ECU and such or is it more!

Most of the power gains come from the 3-stage intake manifold. The problem with the conversion is finding someone to flash the ECU to work the 3-stage intake. The ECUs are matched to the VIN so you can’t just plug in a SI ECU.
