F.I. Tech or Holley sniper. Opinions from users.

I have no doubt the FI is going to give better drive-ability over a carb. But there is a reason the OEMs went from TB to port injection and probably not because it was cheaper. I guess I was more interested the TB vs Port and if there was any HP advantage, throttle response, fuel economy, etc and if so, how much.
From what I understand, port injection will allow for a leaner idle. I can and do run mine right at stoich. It also idles fine leaner than stoich. I don't have any experience with TBI, but I've read they need to idle slightly richer than stoich. I'm curious to find out the validity of this based on others experience. I also think port injection allows engineers to get creative with intake manifold designs to optimize HP and efficiency since they only have to worry about air flow and not fuel flowing through those complex designs.
