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.

B58 Beast

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.
