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 probably need to re-enable those flags. Still working on a completely dialed in VE Table but this should be a good place to start for anyone that wants to use this strategy. You probably need to turn down the A/C fan load in this, I keep forgetting tbh.

I am green tuner and my strategy could harm your vehicle unintentionally. DO NOT INSTALL FOR DAILY DRIVING (still developing this into a more stable tune with a truck that I can afford to blowup)
