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!

Mind numbing torque at your command

What’s even more impressive when having an Alpha file installed on your 550 Series Mercedes-Benz is the monstrous torque that you will have on command. Through our non-invasive update to the powertrain control module (PCM), your AMG will produce 660 ft-lbs of torque! To put this in perspective, that’s a 98 ft-lb gain! More importantly, power is dramatically increased throughout the engine’s entire rpm range. Our Alpha file will provide you with power that you can feel no matter what rpm you decide to punch the throttle.
