550 Series V8 (CL,CLS,E,GL,ML,S,SL) - Calibration
With its stout design, the Mercedes Benz 4.6L V8 Biturbo engine provides excellent luxury class power for the 2011+ Mercedes-Benz lineup. The stock output of the M278 engine is rated at 402 horsepower and 443 torque or slightly more, but these engines are quite underrated from the factory.
More power than the 991 Turbo, made easy. An Alpha calibration file will take full advantage of your 4.6L BiTurbo’s ability. By precisely adjusting camshaft timing, boost output and air/fuel ratios, your M278 equipped 550 series will produce an incredible 575 horsepower with no other form of modification!
