You guys should check out

They're late in getting this thing ready, but they have way better technical info on their site than anyone else. I like their prices, and how "clean" the installs seem to be. They offer new injectors, and a re-flash of the factory ECM rather than a piggy-back add ons. They claim less wiring.
As of today they think it's still a couple more weeks of time before the last of the parts are in, in order to sell the complete kit.
Notice the tech info on the site as it relates to the air/fuel ratios of each cylander when you add a 9th injector into the dry manifold.
You have to look around their site to find the tech sheets, but they're really interesting to read once you find them.
