Based in Orange County California, Weistec Engineering is one of the best up-and-coming Mercedes-Benz tuners in the United States.
They were the first tuning company to safely upgrade the 5.5-liter twin-turbocharged M157 engine from the Mercedes-Benz E 63 AMG W212 to a massive 850 hp.
Their most impressive modifications would probably be the ones they did to their own C 63 AMG Coupe Black Series though, which is now probably the fastest of its kind in the United States.
The legendary M156 normally aspirated engine from the C 63 was transformed into something even more spectacular with the help of a Stage 3 supercharging kit, bringing its total output to a not very round but very impressive 769 horsepower and 918 Nm (677 lb ft) of torque.
