Based on my trolls of the posts on the AudiWorld B5-S4, the consensus is NO. But, u will have to fiddle with the fueling to get the same low grunt of the K03. 
Many guys (on the AW B5-S4 forum) use Lemmiwinks to modify air/fuel & timing on Stage 3(and "3-minus") set-ups. In fact, I've used Lemmiwinks to "tweak" my Stage 2++ set-up. You can definitely feel the difference after making Lemmi tweaks to an already potent set-up. 
NO WAY can u reproduce the power and feel in a stock set-up. Granted, tweaking the timing and fueling via Lemmiwinks on your S4 is NOT FOR THE FAINT OF HEART or un-initiated.

So the K03 kicks in about 1800 rpm ...

Isn't the K04 something like 3500 rpm before boost
kicks in?

I like the snappy feel of the stock K03 (not saying I
wouldn't go the K04 route when the time comes), it
gives the car a very quick feel. Is that sacrificed
in the K04 setup?
