Hey Ratsnst1,
I respectfully disagree. During engine break-in or after it has a few miles on it there should be no reason for the timing, fuel mixtures or whatever to vary from the original settings.
Some folks use a soft tune up until a they have a few miles on their baby but if anything moves it was not tight or it is breaking. I think it is a good idea to be a little conservative with timing and on injected engines set them a bit on the fat side.
I bet the Roush Boys could squeeze a little more HP out of their engines for the track but why push things for the general public on a warranted engine. Also bet it makes every bit of the advertised spec's even with that soft tune-up.
