B58 Stage 3 Tune

Name: B58 Stage 3 Tune
Brand: Rapid Racing

Custom calibration · E50–E85

Upgraded turbo. Logs-first, always — built around your datalogs. 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.
