If a SLK320 has the same motor and the same EXACT factory code, what would the issue be? If there was any nuance between the two cars they would at minimum install different software.
There are numerous ECU codes for the crossfire, and within those ECUs there are numerous versions of software. Some match up with the SLK320, most do not. We verify what is installed on each car and install the proper tuned file. We are not stuffing "random" SLK files into your ECU.
There is a 30-day money back satisfaction guarantee on the tuning.
