Interesting. I found the stock tune for a 2006 mustang 4.0l. Very different from ranger.

Well. I'm not crazy. As soon as I go to WOT, all spark is pulled to below baseline.

Again it's been awhile...
But when you go to WOT... the PCM is gonna pull some spark while under load.
If I'm reading it right... that's exactly what happened.

You are. But negative seems off. Might not be.
Update is I found where it falls off. When the truck switches from cold base to base fuel table, there's a noticeable power difference. Makes sense.
