For sale is a 100% new, uninstalled RaceChips “GTS Black +” Performannce chip upgrade for the Mercedes 2.0 L / 255HP engines found in the GLC 300 and C300 (and others).
According to manufacturer, adds +54hp and 30% more torque. It is my impression, likely wrong, that it accomplishes this by modifying the behavior or the electronic waste gate and fuel mapping.
For those who don’t know, RaceChips makes awesome products.

Car is gone, engine chip sat in the closet waiting for install that never happened. Install requires three connectors to be unplugged, then plugged into RaceChips harness, and then you are ready to run.
