Race Chip GTS Black Chip tune

RaceChip Tuning Box Kits welcome you to a different league in engine performance tuning. Discover a whole new driving experience with RaceChip.  Manufactured in Germany, Autobahn tested, and dyno proven, these technologically advanced kits can sometimes out perform ECU remapping. Once installed, you get more power, greater torque, superb mid-range punch, stronger acceleration and quicker responses: you’ll love the new characteristics RaceChip chip tuning will give your car.  RaceChip tuning doesn’t simply turn everything to the max – it optimizes intelligently within your engine’s design limits.

Plug-and-Play performance upgrade for your 4.0L engine (503 hp) from the Mercedes-Benz tuning expert. Get up to +92 hp and +148 lb-ft.

Even nominally identitical engines often perform slightly differently. This can be down to manufacturing tolerances, the number of miles covered or the quality of the fuel. So that your RaceChip works perfectly with the engine in your car, we have developed fine tuning mappings. They mean that you can fine tune your GTS or GTS Black to match your engine’s performance and characteristics perfectly. The app control feature lets you download the pre-programmed settings right from our servers.
