Here's a split second dyno run done by Grass Roots Motorsports mag:
Ideally you should tune on a dyno and then lock down the settings.
I took a different direction and went with aftermarket engine management. I'm using a Link Electrosystems AFM/Link to run Alpha-N with Map sensore correction to avoid the low throttle/low RPM issues with straight Alpha-N. I'm an experienced tuner though and had to do lots of datalogging and the like. I can now also ditch the plenum and make or buy a composite piece. The stock AFM and alloy plenum together weigh well over 10 pounds BTW.
So for most folks, a mass air kit is the easiest route to take. One advantage of mass air over what I did is that as you make mods it can compensate to a large degree.
