Is the tune necessity something associated with berk or HFC's in general?

There's a "rule" that you need a tune if you do Intake/HFC/CBE because it is usually enough to throw your a/f out of whack to where it needs correction. It's possible that you might need a tune after just two of the three, but in general you're usually OK unless you do all three.

Ok... I usually do just intake and exhaust and leave the HFC off so I don't have to deal with swapping cats at inspection time. I ran a tune before but I did it to get higher revs out my my G'S

I leave the cats alone on all of my street cars.
