Mercedes Tuners CLS63 AMG Mercedes Tuning

As you can imagine, as Mercedes tuners, we love a good tuning story. Today we’ll recount Mercedes Tuning of a 2012 CLS63 AMG. Upgrading the performance to a whopping 665 horsepower. Here’s how it all went down.

Factory Specs

From the factory, this CLS63 AMG already had something special going for it. Particularly because the owner chose the performance package. Coming into the PRESSERtech Mercedes Tuners garage, this CLS63 had 550 horsepower and 590 LBS-FT torque. That’s simply amazing. But if you know us, we’re here to perfect what’s already great, and take your vehicle to its truest potential.

When our CTO Todd Presser took the CLS63 out for a spin, it was obvious that despite the incredible numbers on paper, this AMG was missing a little bit of kick. “I can tell this thing has a lot of lag going on with it,” Todd said during our video of this tuning story. “This thing should just be jumping up when I hit the gas in sports mode.”

And as you can see at the 2:10 mark of the video, Todd couldn’t wait to get started tuning.

The Pressertech Mercedes Tune

There is no one-size-fits-all approach when it comes to performance tuning. A stage 1 tune on this car would increase the horsepower to 580 and the torque to 627 LBS-FT. This particular client chose a stage 2 tune. The Stage 2 Tune would produce eye popping numbers. Increasing the performance to 665 horsepower and 730 LBS-FT torque. Now that’s a Mercedes Tuners dream.

Now came the fun part for us. In the garage, Todd worked with the CLS63’s electric control unit (ECU) also commonly known as the electric control module (ECM). When Mercedes Tuning, whether we’ve popped the hood of a C-Class, E-Class, or another series. This process requires Mercedes Tuners to have an intense attention to detail and careful precision. When looking for the best Mercedes tuning company for you, you want to make sure you’re working with a specialist, who has a strong background in engine tuning. Once the ECU is removed we make sure it’ in good working condition by running diagnostics (we can also help with a ECM repair if needed). Then we read the ECU with special programming tools and work on the Mercedes tuning file.

The Results

And now it was time for the big reveal. After tuning the CLS63 we saw a 20% increase in horsepower. For this vehicle that meant a total 665 horsepower, and while we could think of a lot of ways to describe this tune, we’ll leave it simply with Todd’s words: “Good god, this thing is awesome.”
