Overview
The modern twin turbo S63 V8 responds extremely well to tuning because BMW leaves meaningful margin in the factory torque model, boost targets and thermal management strategy. Stage 1 alone turns these cars into a different class of performance machine while preserving stock drivability and start up behavior. Stage 2 with downpipes and cooling support unlocks a very large top end improvement and is especially compelling on heavier X and Gran Coupe applications.
Key Features
- Luxury performance halo
- very large torque gains
- bench workflow
- top tier clientele
- big Stage 2 upside
