Your G80 M3 makes 473 HP — the M3 CS makes 543. Same engine, different software.

• You’re sitting on an S58 that BMW already validated for 543 HP in the CS model — but your standard M3 only gets 473 (or 503 in Competition)?
• The top speed limiter cuts you off at 250 km/h when the car is clearly capable of much more?
• You want CS-level throttle response and exhaust character without the $30,000+ premium of buying an actual CS?
