If we are assuming soot build up in the cats can be purged via WOT pulls I think that's a solid vote FOR doing an Italian tune up right? Clogged honeycombs in a cat can wreak havoc on downstream o2 readings and in turn impact fuel/air ratios.
Do I think I'm restoring a 10% HP loss by flooring it? No, of course not but again I do think there is value in touching the entire rev range from time to time. Especially on cars that never see that kind of use. Besides, it's really fun to do!!
I do agree you aren't impacting any carbon plaque that may have built on the top of the intake valves.
