horsepower is horsepower...if you're making 500awhp with 20psi and 30* of timing it's no safer on the internals than 500awhp with 30psi and 15* of timing if both pushing the limits of the octane.
If your tuner is quelling knock with fuel, they don't know what they are doing, that's a different issue.
btw, these figures are just an example, not real.
