I've always herd, when they go bad they crap the bed completely. Clearly not the case here.The Ford tech I had flash my old one said this was the first one he's ever seen behave this way.
Glad to see its running hard for ya buddy!
Seat time at the track in general will help get that thing dialed in. I've never had any luck going by RPM, but everyone's different.
Refreshing to see a truck that runs as good at it looks!
