CS Performance DME Flash - BMW G8X M3/M4

Aimed at BMW G8X M3/M4 owners, the BMW CS Software flash upgrades the your M3/M4 to the CS software tune, with the following highlights:

Features

• No need to unlock ECU – Plug-and-play flash; no opening or removal of DME
  OEM CS software flash
• Not aftermarket tuning, but genuine BMW software from the CS model
• M3/M4 xDrive CS Power bump – From ~453 hp to 530 hp, and torque from ~550 Nm to 650 Nm
  
• Idle slightly increased from 600rpm to 900rpm
  
• Top speed limiter removed – Now limited only by gearing/aero (~186 mph or 300 km/h)
• Dealer-safe – No tuning flags triggered (e.g., BMW’s tamper detection won't record as modification)

For xDrive configurations only. While this may not trigger flags, BMW can still deny warranty claims if they determine the car is running different software, especially if a fault is software-related.

Note: Vehicle coding is performed in our facility in Anaheim, CA. Not available for home or remote-based flashing.
