4 Barrel FI kits for a /6 Turbo setup

I'm running through some things for my car and I've stumbled across a deal on a Offy manifold and a set of headers I could use to weld up a turbo setup for my Slant instead of diving off into the 5.7 swap. But I've been combing the Forced Inductionsection looking at all the throttle body injection setups and haven't seen one yet that ran one of the 4 barrel fuel injected kits. I've seen a lot of these setups geared towards alot of the V8 guys and kind of catered to them. But I've been looking at setups like this one from Professional Products and its their Projection III kit(http://www.summitracing.com/parts/pfs-70026/overview/) and after getting off the phone with them they confirmed it had a 6 cylinder option on the menu and that the base tune could help get it running and then tuning from there via a laptop which would be the best option for when youd like to turn the boost up a little bit to make some more power. I figure one of these would be a good starting point but haven't quite cleared up how it would tie into the existing ECM already running my slant 6. I may be the test dummy for everyone if I can dig up any info on it prior to the teardown of the car. Any help or advice?
