At the W205 you have either the OM651 (2.1 litres) or OM654 (2.0 litres). The OM626 is uninteresting. What version do you have? The chips for plugging are the cheap and unprofessional method. If you are interested in a reputable performance increase, you should take some money in your hand and look for a specialist company that will give you another software.

In the “correct” chip tuning, the characteristic line of the turbocharger is simply changed so that it earlier generates a higher charge pressure.

This should be done by a professional who looks at the overall view.

These race chips and their names are more of an emergency solution.
