With its stout design, the Mercedes-Benz CLA/GLA/A 45 Series AMG engine provides excellent entry level luxury class power. Mercedes-Benz rated the stock horsepower output of their 45 Series AMG at 375HP and 350ft/lbs, but these engines are very under rated from the factory. The AMS Alpha completely stock 2014 CLA45 AMG made 401HP and 363ft/lbs! But, AMS found a way to tap into the hidden power of your A-Series AMG!
An Alpha calibration file paired with the Alpha Performance Downpipe, and Alpha A Series Filter will take full advantage of your AMG's untapped potential. By precisely adjusting camshaft timing, boost output and air/fuel ratios, your 2.0L turbo equipped AMG will produce an astounding 454 horsepower!
Not a Generic Off the Shelf Tune
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 update to the powertrain control module (PCM), our Alpha Performance Mercedes-Benz A Series Downpipe, and Alpha Filter your AMG will produce 491 ft-lbs of torque! To put this in perspective, that's close to a 130ft-lb gain! More importantly, power is dramatically increased early in the powerband and is sustained 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 mash the throttle.
How Does It Work?
Just like all cars using an Alpha calibration file, your AMG 2.0L 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. In order to tune your A Series AMG you need to remove your PCM. You then send your PCM to AMS where our industry leading Engine Calibrators will add the Alpha Performance tune to it and send it back for you to reinstall. Turn around time is an amazing one day.
