Description

The Turner Stage 1 performance software is an engine tune for the E60 M5, E63/E64 M6. It optimizes engine programming for higher octane fuel (91 or 93) and includes features like revised fuel and timing maps, improved VANOS variable valve timing, and a smoother pedal response. The software also offers an optional raised rev limit of 8,500 RPM, allowing for longer gear engagement.
