B58 M240i (G42) on Mustang dyno:

• Stock: 310whp / 460Nm
• Stage 1 (BM3 OTS map): 395whp / 570Nm
• Stage 2 (BM3 + VRSF DP + CSF FMIC): 455whp / 630Nm

The B58 is absolutely insane. Stage 2 numbers that would have required a turbo upgrade on the N54/N55. And it's completely stock internally.

S55 F80 M3 on Maha dyno:

• Stock: 380whp / 520Nm (BMW underrates these from factory)
• Stage 1 (Bootmod3): 470whp / 620Nm
• Stage 2 (BM3 + catless DPs + FMIC): 530whp / 680Nm
• Stage 2+ (BM3 custom + DPs + FMIC + intake + charge pipes): 555whp / 710Nm

The S55 makes stupid power with just bolt-ons. The stock turbos are the limiting factor - they run out of breath around 560whp.

Diesel results from my cars:

N57 530d (F10) on Dynojet:

• Stock: 235whp / 560Nm
• Stage 1: 290whp / 650Nm
• Stage 1 + DPF delete: 305whp / 680Nm

B57 540d (G30) on Dynojet:

• Stock: 295whp / 620Nm
• Stage 1: 355whp / 740Nm

The B57 is a monster. 740Nm of torque from a stage 1 tune is just ridiculous. The car pulls like a freight train from 1500rpm.

E46 330i (M54B30) on Dynapack:

• Stock: 195whp / 270Nm
• Intake + exhaust + tune: 215whp / 290Nm

Naturally aspirated gains are modest but the car feels much more alive. The M54 responds well to a good intake and a proper tune that optimizes VANOS timing.

For comparison, my friend's E46 M3 (S54):

• Stock: 310whp / 340Nm
• Full exhaust + intake + tune: 340whp / 365Nm

NA engines just don't make the same percentage gains as turbo cars.
