Been working with efloth over on fordsix forums, I wanted to bring this over here and post the latest updates to this strategy. My motor setup has all the emissions removed, if you are using this and have emissions equipment installed you need to re-enable those flags. Still developing this, about to start digging into spark and air (idle air/dashpot) next. Slowly dialing in the VE tables over the next couple days.
