Is it even worth it for a bigger mass air meter on a stock engine with a CAI setup?

There seems to be something about MAF rotation. Densecharger was having trouble with their positioning and have (or ar about to) change it.

Rotating the MAF for induction bend issues is quite common on many applications.
Unfortunately, when using a stock "flanged" type MAF, rotation is somewhat limited and sometimes impossible... this depends on the flange size and application.

Most owners with blowers like to use "bullet" type MAFs for un-hindered rotation while tuning with their setup.... this is due to the sensor usually being placed at the "top" of the MAF unit, which in some applications may not be the best angle to get a good reading.

This is the same basic principle when encountering possible CAI\MAF problems...

The Pro-M "Univer" MAF is a good solution for blown applications as it "should" be able to get a good reading no matter how the MAF is positioned. (Of course with this also... Mileage May Vary...)
