    Mercedes Tuning CLS550 4.7 Liter Twin Turbo W218

    Mercedes Tuning of a 2013 CLS550 Coupe 4.7 Liter Twin Turbo W218

    Like They Say, We’re Here for the Best or Nothing: Tuning the CLS550. When the Vision CLS concept car dropped at the Frankfurt International Motor Show in 2003, it was “a coupe generation ahead of the rest.” The CLS rolled out for the first time in 2005, marking a return to the executive-size coupe market for Mercedes Benz. Today we’re looking at how a Mercedes tuning performance tune can enhance this second generation 2013 model with the W218 Chassis.

    At stock, this car already has impressive stats. It’s powered by a 4.7-liter twin-turbocharged V8, with 402 horsepower and 443 LBS-FT torque. As a mid-size luxury 4-door coupe, it zips up from 0 to 60 in 5.2 seconds. It’s even got an analog clock on the dashboard, adding some old school class. Certainly AutoTrader summed it up best by calling it “an unprecedented combination of style, sophistication and strength.”

    Now to the fun part – seeing how our Mercedes tuning can light a new fire in this 2013 model. As car technology becomes more complex, we can make a big difference to engine performance without expensive upgrades. So much of your car’s performance is being controlled by its engine management software. As Mercedes Tuners, when we talk about our tunes, we talk about them in terms of stages. A stage 1 tune would upgrade this CLS550 to 510 horsepower and 605 LBS-FT torque. That’s 26% more horsepower and 36% more torque, which is really quite amazing. (We have Stage 2 tune options as well for even more power. Just reach out to us for more details.)

    Now for the fun part of Mercedes Tuning this CLS550 with the Twin Turbo W218

    To amp up this CLS550, we brought it into our shop and modified its ECU, ECM also referred to as a ME (your electronic control unit). Our base Mercedes tunes are tested and developed on a MAHA dynamometer. We always follow the original safety margins of the specific model we’re tuning (read: the opposite of this). You also have the option to upgrade to the ECU+ package and keep your old ECU with the stock tune.

    After carefully removing the CLS55’s ECU, we analyzed and adjusted the engine management software. This engine software is largely responsible for the vehicle’s performance and fuel consumption. We tailored the programming to provide more power and torque, which led to smoother acceleration and improved throttle response.

    In Conclusion

    This 2013 CLS550 is now energized and ready to hit the pavement with 102 more horsepower and 162 more LBS-FT torque. The owner will also see an added benefit of improved fuel efficiency. At PRESSERtech, we’ve spent nearly 30 years working on Mercedes Benz vehicles. We also have a variety of other services. If you’ve got a bad ECU, we can fix it with a Plug and Play M.E., or we can pair a Virgin ECU with your vehicle. You can learn more about our services on our About Us page.

    Each Mercedes tune we perform is optimized for your individual car and guaranteed for life. Check out our Select Tune page to find your model, or just give us a call. We’re always ready to answer your questions and point you in the right direction. Every Mercedes tune is unique to you.

    Weistec M157 W.4 Turbocharger System Overview

  • M278: M157 AMG turbochargers successfully swapped onto C218 Mercedes CLS550 M278 4.7 liter V8
  • Gardevski doesn’t give all the breakdowns in full detail on his build thread, but he does state the m278 is identical to m157 except smaller bore, smaller turbos (but 278 has a higher flowing turbo manifold as he states). He owns both cls63amg m157 and cls550 m278. He basically had to upgrade IC pump, heat exchangers, AMG fuel pumps, AMG brakes, and body kit for heat.) this is for the basic upgrade which many have done just the turbo swaps since he already took the risk and others with the m278 have seen massive dyno gains due to higher compression ratio. Still not an AMG vehicle by any means, but still very impressive motors. Very interesting build thread y’all should check out! He custom designed an entire new setup for both m157 and 278. He’s just now tuning the new setup and real world results he states will be posted with additional info. Definitely worth the read!


    Upgrade cls550 turbo

    Standing straight down the strip looking at the front of the CLS550 and CLS63, only the well versed Benz enthusiast will know which is faster.  The CLS550 comes with the 4.6-liter V8 that boasts twin Honeywell GT2260 turbochargers and direct injection that join forces to create 402 horsepower.  The CLS63 brings to the table a 5.5L V8 Bi-Turbo that produces 518 hp at 5500 rpm and 516 lb-ft of torque at 1750 rpm.  So without spending the extra $40K, how can you make your CLS550 beat up a CLS63…  By getting a VRTuned ECU Flash.  The ECU is really easy to remove from the car and requires it to be bench flashed.  You can see from our instructions how simple this process is here.  After the ECU is flashed, expect to see your 4.7L V8 go from 402bhp to 480bhp with over 500ft/lbs of torque. 

    With the VR Tuned ECU Flash we adjust the cars boost, fuel, and timing tables.  Giving you a very driveable, reliable, and powerful upgrade.  In addition to the basic performance tuning, we can also tune for catless downpipes, raise your top speed limiter, and change your torque limits to give you much faster throttle response.  All of this is available from VR Tuned for $1500 which is almost 50% less than the competition!  Check out this customers vehicle below.
