Ok, remember I said effective power. I am not suggesting that a higher ratio diff increases actual engine HP.

What does happen is that the higher ratio increases torque at the wheels for a given engine RPM.

The bottom line is that your 328 will pull better, now you will lose top end, but any top end you lose would be illegal here so all in all it's a great upgrade, and it's relatively cheap.
