To RS2 or Not? (longish)

To RS2 or not to RS2, that is the question. . . .
Over the course of the past few years I've been carefully upgrading my
'91 200 20v tqa so it would be ready for an RS2 conversion. Among other
things, I did the suspension; the brakes, added a custom mandrel bent
exhaust, and the IA Stage III+ ECU. I've also contacted a good friend
in the fatherland and have obtained fantastic RS2 pricing. Now that
order day is upon me, I'm having second thoughts. Why? 95% of the time
I live between 2200 and 3200 rpm. I did a bit of charting this weekend
using Jeremy Williams IA Chipped '91 200 TQ Dynograph that's posted on
the S-Car list Yahoo site (files/jeremy_audi.jpg) and RS2 Dynograph
that's also on the S-Car list Yahoo site ( Photos/RS2-UrS4 DynaPack)
From these two graphs, here's what I've *estimated*
Torque: RPM/K24/RS2
2000/190/120
2500/210/135
3000/255/170
3500/270/260
4000/286/350
Torque conclusion: the K24 hammers the RS2 until about 3500, then the
contest is over.
HP: RPM/K24/RS2
2000/75/60
2500/100/70
3000/150/120
3500/180/200
4000/210/325
4500/250/360
5000/273/394
HP conclusion: the K24 hammers the RS2 until about 3500, then the
contest is over.
Query: Is it fair to say that the K24 outperforms the RS2 until
3500rpm? If so, I'm not sure I want to RS2. Number don't always tell
the whole story, so I'm looking for lots of input from you RS2 guys.
TIA for your help and collective wisdom,
Greg J
