M157 5.5L Biturbo ECU Tune By ALPHA VCS



With its stout design, the hand-built Mercedes Benz AMG 5.5L V8 Biturbo engine provides excellent luxury class power for the 2011+ AMG lineup. Yet, with stock output of the CLS63 detuned to 518 horsepower, there’s certainly room for improvement.

More power than the Lamborghini Gallardo, made easy. An Alpha calibration file will take full advantage of your 5.5L Biturbo engine’s ability. By precisely adjusting camshaft timing, boost output and air/fuel ratios, your 5.5L Biturbo equipped AMG will produce a massive 701 horsepower with no other form of modification! That’s 141 more ponies than a Lamborghini Gallardo!

Unleash the power the factory held back. Order your Alpha Calibration today!

Mind-Numbing Torque at Your Command
What’s even more impressive when having an Alpha file installed on your AMG is the monstrous torque that you will now have on command. Through our non-invasive update to the powertrain control module (PCM), your AMG will produce 830 ft-lbs of torque! To put this in perspective, that’s a 312 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.

Big Benefits, No Compromises
Just like all cars using an Alpha calibration file, your AMG 5.5L equipped Mercedes will exhibit smooth, stock-like drivability. The only difference is a dramatic increase in power and acceleration. What’s even better is that you’ll be able to enjoy all this with no detrimental effect to fuel economy at partial throttle or cruising speed.

Our race winning experience creates higher standards
At Alpha tuning we write our own files and use our years of race winning experience to bring something new to the market. Such knowledge allows us to optimize every aspect of the way that your car drives. We calibrate your ECU with a level of expertise that most others simply do not possess. Making finely tuned adjustments to cam timing, fueling, ignition timing, load control, throttle mapping and boost with a real focus on the overall effect to the driving experience, instead of just loading in a canned tune that is commercially available. What’s more is that we are able to provide you the highest level of performance with no sacrifice to reliability.

Not your typical generic tuning solution
Most tunes available are generic, rebranded, “solutions” that come from one of a few sources. Typically these tunes are developed more by software engineers than seasoned race engine specialists. As an enthusiast why would you settle for the same run of the mill results?
