The 2.9 in the S is the same 3.0 block just bored slightly over is my understanding. I drove an '11 B8 S4 that I bought new and tuned and tinkered with for 10 years, that's a great engine. Why thy went away from supercharging I'll never understand, I much prefer it.

2.9 has a lower compression ratio than the 3.0. In order to achieve more tq and pwr bmep must be higher therefore fuel delivery+boost at stoich is higher than the 3.0.
