Has anyone ever tried this unit? I am planning on installing it this winter on my 383 for a little more performance and to control nitrous.

Well, I work for the outfit you linked to, but this one did get used on a C4 Corvette when they were testing it out. They have their application notes here:

It'll run pretty much everything on a SBC except the stock idle air control valve, and you can just prop the idle speed set screw open a bit or swap on a BMW IAC valve to get control over the idle speed.
