Default LS1 MAF sensor in C4

Has anyone replaced their C4 MAF sensor with a LS1 MAF ? I have read elsewhere that it give much better driveability and more power. Have not been able to find great documentation on this.

C4 MAF's are voltage based - C5 & newer are frequency based .........

The 94-96 MAFs are frequency-based, just to be perfectly accurate.

We have had some limited success with analog slot-style mafs in 86-89 C4s, however:
