An SL550 Performance Tune in a Brand New PRESSERtech Shop

You may know that PRESSERtech, home of the Performance Tune. recently moved. Our new digs have a comfy waiting room for you to relax while your car is getting a Mercedes tune. Of course, we’re also pretty excited about our new garage. We couldn’t wait to break it in, and we could think of no better housewarming than giving a 2014 SL550 a performance tune.

We were excited to Mercedes Tune this twin-turbocharged 4.6-liter V8 engine, this white 2014 SL550, with camel interior, came into our shop with 429 horsepower and 516 LBS-FT torque. It already can go 0 to 60 in a blistering 4.5 seconds, with a top speed of 130mph. And yes, we can top that with a performance tune by the Mercedes Tuning experts at Pressertech.

History of the Sportlich-Leicht (Mercedes SL Class)

But first, some history. Because the SL-Class has been around for a long time, tracing its roots back to 1952 with the W194 racing car. This was Mercedes first post-war competition car, and while it lacked power, its lightness made it a successful racing car. As a matter of fact, the designation SL comes from the German Sportlich-Leicht, or Sport Lightweight. The 1954 300 SL is considered the world’s first supercar, which had a top speed of 154mph. The SL was even the car of choice for one famous soap opera oil baron.

Starting in 2013, the SL-Class was produced almost entirely from aluminum, with a retractable roof made of magnesium. In the true meaning of SL, it’s 240 pounds lighter than its predecessor. Fifth Gear called the modern SL-Class, “a car for cruising around, looking groovy.”

Building the Performance Tune

In our new PRESSERtech garage we performed a Stage 1 tune on this SL550. Our goal was to increase the horsepower to 550 and the torque to 627 LBS-FT. We also can perform Stage 2 tunes if that’s a better fit for you.

The key to tuning is the electronic control unit, which dictates how effectively the engine can run. Mercedes engines are often depowered in the factory to allow for consistent performance increases on new models year after year. But that also means that there’s probably some untapped potential in your Mercedes engine.

Results for Days with a Mercedes Tune

The tuning upgrade results for this turbo charged gasoline engine are simply amazing. We saw a 28% increase in horsepower and a 21% increase in torque. Our clients also typically report a reduction in fuel consumption, smoother acceleration and a much-improved throttle response.

Our tunes are also 100% customized to you. If for some reason the tune doesn’t meet your expectations, we can always go back and make tweaks. Additionally, if you want to keep your old ECU with its original stock tune, you can upgrade to an ECU+ package.
