Great Solution that raises some more questions. First, when you tweaked the butterfly adjustment down to the absolute minimum, did you have to visit the idle speed on the monitor and bump it any to compensate? Second, where on the unit did you go to make that adjustment? Third, my own AFR is at about 12.7 or so with the engine warm. If the hand-held does show it at around 13-ish, it is usually a case of it being a cold engine on initial start. As the mill warms up, the AFR automatically leans itself out to the correct ratio. Fourth, your motor being a 350, the settings that give you the best responses may prove to be different for larger or smaller motors or built motors as opposed to stock or crate mills. Fifth, still looking seriously at my own fuel system as being THE culprit as fuel starvation displays a lot of the symptoms that I am experiencing and the 1st edition FI-TEch booster pump never did strike me as being the proper solution to begin with. (I hate budgets) As for my solution, Holley makes an electric pump in-tank pump that only requires a single hole to install; no ring of smaller holes and a mounting plate and additional drilling. It also comes with a dedicated return circuit that will allow me to decommission what FI-Tech originally suggested which was to repurpose the vent plumbing because the factory in tank pickup wasn't suitable according to them. The big hassle will be to drain and dry out the tank so that it can be drilled safely. May take using another new tank to accomplish that. Bummer.
And of course, Murphy has to stick his nose in; i.e. "when you have a budget, you don't have the time." Plus the forecast is for another 10 inches of white crap to descend upon us. "For what we are about to receive, we thank Thee."
