Sequential Multiport EFI

yeah I've seen that site but it's only cpu stuff no pumps or jets or rails etc... ,there was quite a bit of talk about using stuff from dakota's and mixing and matching parts but I'm looking for a complete setup the Eddy kits have everything including the dizzy , I am wondering if anyone has done business with Affordable EFI because they are 1000 bucks cheaper than the Eddy setup on Summit , and I need to know what I should be buying to upgrade the kit to support 550 hp since all the kits I see are designed for 450hp for the Mopar small block .I was hoping some of the guys who have played with these systems would chime in .
