Basically something that adjusts the MAF readings to fool the ECU into feeding more or less fuel. To make it really really simple, you're changing the voltage being sent to the ECU to adjust fuel ratios.
Either vehicle you'll likely need an EFIE or other form of modification - but I still vote for the vic. Hell, if anything see which one has more room to play in. My Maxima is no fun, I think it was designed and built to be worked on by Smurfs.
