Let's build a community database of real dyno results. Post your before/after numbers with your mod list.

I'll start with my collection from cars I've tuned:

N54 335i (E90)

  • Stock: 278whp / 390Nm
  • Stage 1 (MHD): 340whp / 480Nm
  • Stage 2 (MHD + catless DP): 385whp / 520Nm

B58 340i (F30)

  • Stock: 295whp / 440Nm
  • Stage 1 (BM3): 380whp / 540Nm
  • Stage 2 (BM3 + DP + FMIC): 430whp / 590Nm

N55 335i (F30)

  • Stock: 270whp / 400Nm
  • Stage 1 (MHD): 330whp / 470Nm
  • Stage 2 (MHD + DP): 365whp / 510Nm

N20 328i (F30)

  • Stock: 218whp / 290Nm
  • Stage 1 (BM3): 265whp / 370Nm

B47 320d (F30)

  • Stock: 165whp / 370Nm
  • Stage 1: 210whp / 460Nm

All numbers measured on a Dynapack hub dyno. Ambient temp ~20C.

Post your results below - include the dyno type so we can compare fairly.

    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.
