The Mercedes-Benz SLS 63 AMG has a 571hp 6.2-liter V8. You'd think that'd be enough. For mcchip-dkr tuning, that just doesn't get the job done, so the company developed the the “MC700” compressor kit, which is available in two options. In addition to the compressor, stage 3 software was added, as well as a performance exhaust system. The lower level puts out 680 horsepower and costs about $91,000, while the 706hp version will set you back $104,000.
