Most people don't choose to mod the 3.0i, if they wanted more performance, I'm sure they would have gotten the 4.4i, I regret not getting it. But if you're going for a supercharger, get the ASA 3.0i kit. It will bring you to about 4.6is/4.8is numbers, for around $7000 installed.
I plan on doing this, if not in the summer, then around fall or springtime next year.
