The long awaited software upgrade is now available for the B7 RS4!
 
The DMS Automotive upgrade brings the output of the RS4 to 328kw of power, and 461Nm of torque. This is up from the already-impressive 309kw and 430Nm. Other benefits include better throttle response, and better drivability due to the additional available torque throughout the entire revrange.
