Just my two cents on this one...

I agree that the overall de-tuning has a detrimental effect, but you
can't tell me that the smog equipment is not the major culprit in the
loss of power department. I have quantifiable "seat of the pants"
evidence to prove it's so! Granted, perhaps the cat was slightly
plugged, or the PCV stuck or something, but when I ripped the smog crap
out of my BMW Alpina it was MUCH more powerful.
If smog junk had any positive effect, wouldn't race cars use them?
