N54 Stage 1 Tune

Custom calibration · 93 pump / E30

Stock hardware, full send on pump gas. The every-day calibration. Built per-VIN against your stock read, flashed with MHD or bootmod3-style tooling, and refined from your datalogs. Revision included when the logs say so. Configure yours to pick fuel, boost target, burble, launch control and flex-fuel readiness — or buy this stage as-is and we will confirm the envelope with you before the first build.
