Has anyone used the Barry Grant (BGFuel) throttle body that looks
like a Holley carb? Their sales pitch is: "annular boosters" improve
atomization. The only other aftermarket TB unit I know of is Holley, 
and I see that Howell sells a GM ECU, and harness, to run it.
Any Howell, Holley, or BG first-hand experience out there?  Steve
