That can actually be seen in the power curve as it cuts off on the way to the top of the stage 2 numbers.
Stage 2+ is plenty of fun, and I actually highly recommend going with the BM3 E50 tune. Even without a flex fuel sensor, the car does a fantastic job of keeping fuel trims solid, and timing where it should be.
The car, albeit gutted, walks away from 5.0 mustangs; even a roushe charged (twinscroll) from a 40 roll.
For stock turbo and minor upgrades, the S2+ E blend maps are respectable in the B58.

That sounds like a super fun car, and I heard somewhere that when the car does hit low fuel with BMW it does cut power. Do you think if you redynoed S2 you would've seen an actual HP gain not just torque? Also I hope to see around your build sometime in chicago area it sounds like a beast!
