Todd,

I agree about the FPR needing to be included too, IF the ECU code is
identical to RS2 ECU code.  The RS2 ECU is physically different and
I've heard the software isn't exactly what works best in a UrS4/S6
because of differences programmed into it for different IC and such.

I assumed that Cody's RS2 software is something done by someone like
Ned at IA to correspond to the RS2 MAF & Injectors and to use the stock
UrS4/S6 FPR.  Remember, the RS2 FPR runs a bit lower pressure, so the
stock UrS4/S6 FPR (with the right ECU software) will permit a bit more
fuel flow through the RS2 injectors to go along with that super whammy
turbo that he hasn't told anyone about.

I agree.  Well actually, other parts like exhaust manifold, exhaust
system, and Intercooler are "optional" too, in the sense that they
don't directly affect the ability of the ECU to get the mixture
right on the money.
