Its a classic example of internet placebo effect. These boards (and others I might add) are littered with examples of people changing minor stuff on their cars and claiming massive differences (when I suspect in a blind testing of two cars they would not be able to tell the difference).
And the E46 cdv thing always surprised me anyway. Virtually noone in Europe (where 99% of people learn to drive with MT's) did the mod (or felt it was required), whereas loads of people in the US (where 99% of people learn to drive autos) claimed the stock transmission was rubbish and the cdv removal was essential.
