Re: My tuner says you can't get much more
In talking a long time ago to the former Ford engineer who tuned this car, it was already aggressively set, which is exactly what some of the other folks shared regarding just attempting a tune-only change.
Ford did good on this engine in stock form. Of course, your results may vary as soon as you get into other changes.
