Been tweaking the Bug.

Where the MAF main body is screwed to the top of the air box, the holes are much larger than the two self tappers, so if you loosen the self tappers, you can rotate the MAF sensor several mm. I marked mine first, then rotated fully one way, nipped it up again and tried the car, then the other (you can do this with it fitted to the car) and you'll find one position gives much better road performance.

Guessing it's something like that though on my car the engine note sounds 'lighter' as if it's a bit leaner.
