It looks like the $3000 kit is just a Do It Yourself type starter kit or just the hardware kit, and the $4000 kit seems to be complete with all the other stuff. I'd like to know what they are doing for fuel mangement though. Innovative is actually a pretty reputable company at least from what I've heard and read. But I would also like to see there FMIC and a list of mods to get it to fit

But even if they do sell a kit with the front mount for $4000 they still have no fuel in there and if you tack on the added cost for some type of MIC(Mass Air, Injectors, and Chip) you're right up there with the Streetflight kit. And in IMO I would go with the SF kit being that it has been proven to be a very good setup.
