Mercedes Tuning Perfecting the Power of the Mercedes Benz C117 CLA250

Now and again, we all need a pick-me-up, and sometimes so does your car. In our shop we’ve been Mercedes Tuning or ECM tuning a gorgeous C117 Mercedes Benz CLA250 (watch the video here). It’s beautifully styled, with sleek lines and an excellent sports package. Now a power upgrade was in order to give this four-cylinder an extra boost. Prior to starting our work, we took the vehicle out for a test drive and noticed a sluggishness that could be dramatically improved with the proper Mercedes tuning. And, oh by the way, save our client a couple of miles per gallon in fuel efficiency.

The car arrived at the PRESSERtech garage, it performed at the stock flash, running at about 208 horsepower with 258LBS-FT Torque. We know from our experience as Mercedes tuners that stock settings often need adjustments to reach the car’s full potential. It’s not uncommon for a car to be purposely depowered in the factory. We could feel that this CLA250’s engine wanted to do more and take off better.

Talking to our client about the Mercedes Tuning

Strategizeing with our client, we had a couple of options available. A Stage 1 tune would bolster the horsepower to 250 and the torque to 295LBS-FT, providing a nice boost from the original specs. But we knew we could make the engine run even better than that. The vehicles owner landed on a Stage 2 tune, which would elevate the performance tune to 260 horsepower with about 310LBS-FT torque. We were more than happy to oblige.

Now we had our marching orders in place, our CTO Todd Presser got to work. With an emphasis on the correct methods of Mercedes tuning. You want an expert technician to make the adjustments, and we’ve spent over 30 years maintaining and Mercedes tuning Mercedes Benz vehicles. Most noteworthy, we’re talking about some very delicate work to adjust the car’s electronic control unit (read more about ECUs here).

Starting the Performance Tune Process

The ECU was carefully removed, Todd ran diagnostics and reviewed it with specialized programming tools. Then it was a matter of taking the tuning file and building the tune. Our PRESSERtech dog-in-residence Holly checked in on Todd’s progress as he worked to crack the code on the original factory settings.

Ultimately, the careful tuning behind-the-scenes paid off, with this Mercedes CLA250 performing at a staggering 50 more horsepower and 50 more lb-ft torque than when it arrived at our shop. That’s a 25% increase in horsepower. Just take a listen to our drive post-tune and you’ll hear the results. At 30,000 miles, this Mercedes is performing better than ever before. And don’t forget that by making the engine run better, we’re improving fuel economy as well.

Consequently, Pressertech believes that your Mercedes tune is customized to you.

Todd said, in the video, “if you go with a PRESSERtech tune, you’re not going to compromise everyday comfort… But when you want to drop the pedal, the power is there, the power is better
