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.

I'm a TBI guy and I run leaner than stoich at idle also (14.8) and at or near stoich at cruise (14.6/7). Runs good.

FiTech Go 4 600. Also I had an issue with the ECU that I bought in 2015 and because of the issue they found FiTech (Anthony) is going to warrentee it. Thumbs up to FiTech.
