Electronic superchargers have been tested many times by reputable places and found to be worthless.
You can remove the precats in the secondary pipe (aka, y-pipe)... I'd grab the Cattman or Custommaxima one myself. (or Warpspeed...). Definitely not 30hp though, even when combined with intake and a cat-back exhaust-- it could be close, though. Intake/y-pipe/catback/cams might be another 30whp+ at the high-end, though, although I have not personally verified this myself.
AFAIK there are no ECU upgrades for the 1999.5-through-2001 cars yet. Jim Wolf Technology (JWT) and Technosquare (TS) are the only two companies with ECU upgrades that actually do anything to the 1995+ Maxima, and they haven't bothered to devote the resources to it yet.
