BMW M3/M4CS - DME Software

Looking to add some extra power and performance to your BMW M3/M4 Competition without the hassle of a full remap or DME unlocking? Look no further than the OEM M3/M4 CS DME Flash. With a 33-40hp increase at 6,250rpm and maximum torque of 550nm between 2,350 and 5,500rpm, this modest power upgrade will take your driving experience to the next level.

The technical stuff

The M3/M4 CS DME Flash upgrades your M3/M4 Competition's engine tune to match the increased output of the M3/M4 CS. This results in a peak power increase of 33-40hp and maximum torque of 550nm for a wider rev range.

The best part is that this upgrade uses the OEM CS calibration, meaning that your DME does not need to be unlocked. This makes the upgrade a much simpler process, while still providing a substantial power gain.
