The 320 is a 6 cylinder isn't it? I don't think the M20 is known for it's low down torque, especially in 2L form. I think they usually need at least 3000rpm before they really get going.

My 323i has a flat spot from idle until about 6500rpm, then the limiter takes over :( .

With mods like a K&N you really need to have the Airflow meter set up by a specialist engine tuner. You may need a ECU remap with the exhaust too, both mods meen that the engine requires different fuelling from standard.
