Edelbrock models 1405 versus 1406 carburetors

Thanks! I use an Innovate MTX-L to tune my stuff, and I'm running a 1406 on my Mustang's 289. It's set up pretty well, but occasionally I'll get a bog (it seems to depend on weather conditions).

I have noticed that it's pretty fat at heavy and full throttle (12-12.5:1), but does lean out a bit when hitting the gas, but nowhere near dead lean like yours did. I love to tinker though, so you have some interesting, proven solutions.
