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) you do download this and make it better PLEASE repost your strategy

UPDATED 6/22/2024 Fuel is a lot more dialed in and this strategy seems to be running A LOT smoother than before. If you've downloaded this before, you might consider redownloading this update. Still working on start up idle, might need to retune the idle air again. This is again for a stock motor with emissions deleted, 3* of spark added across the board, extended VE. Make sure your timing is set mechanically to 10*
