German tuner GAD-Motors send us information and three pictures showcasing their improved twin-turbo package for the V8-powered 2012 Mercedes-Benz CLS 63 AMG. The total performance of the kit is 803hp at 5,529rpm and 1,149Nm at 4,114rpm.
The upgrade has been achieved by using a new sports air filter, optimization of the intercooler, enhanced water cooler pump, larger GAD turbochargers (30 percent bigger), exhaust manifold with downpipe and sport catalysts and an optimized exhaust system with valves. The boost pressure was increase and the mapping of the fuel and ignition optimized. The final change is the removal of the Vmax.
