Mercedes Performance Tune for Sporty 2013 Mercedes C-Class 250 CGI W204 Chassis

Are you wondering what upgrades could make a big difference on the performance of your Mercedes Benz? You might consider a Mercedes performance tune. At PRESSERtech, we’ve tuned a variety of models, including this 2013 C250 with charged gasoline injection. Here’s how we increased this vehicle’s horsepower by 19% and the torque by 28%.

The C250 was once described as “an appropriate mix of sportiness, luxury, and class.” As an entry level compact luxury vehicle, it puts up performance and fuel efficiency numbers that are not too shabby, but can definitely be improved by a Mercedes performance tune.

A base C250 model has a turbo-charged, direct-injected 1.8L four-cylinder engine, with 201 horsepower and 229 LBS-FT torque. It’s a fuel efficient and quick car that hits 60mph in 7.1 seconds. The C250 clocks in at 21 mpg for city and 31 mpg for highway.

Mercedes Tuning

When we talk to Mercedes drivers about their cars, we’re always interested to hear about their specific needs. Our Mercedes performance tunes are completely customized to each driver, so no performance tune will look exactly the same. We can promise better throttle response and increased efficiency through all loads, by optimizing engine software. But the tune should really be about you. We can offer different Stages of tunes, depending on how you’re using your vehicle, from real world tasks like every day errands, to a weekend trips out to the track.

For this car, we performed a Stage 1 tune, which would move the needle on performance to 240 horsepower and 295 LBS-FT torque. In order to make these performance upgrades on the C250, one of our tuning specialists made adjustments to the vehicle’s electronic control until. It’s also called an ME in the trade. This procedure started with the careful removal of the ECU. We then ran diagnostics with special programming tools. Finally, our technician built the tune. The base files are developed and tested on a MAHA dynamometer for the best possible performance and results.

The ECU is the key to your car’s performance. By adjusting the ECU we can make a noticeable difference without expensive upgrades. And while you can always add upgrades to your vehicle later, it’s worth trying an ECU tune first. It definitely offers the best bang for your buck.

End Results from Tune

Once the tune was finalized, it was time for the big reveal. We were happy to report that the C250 had a 19% increase in horsepower and a 28% increase in torque. For the majority of the Mercedes we’ve tuned, we see a reduction in fuel consumption, smoother acceleration and much improved throttle response.

Supercharged 2004 C230 Performance Mercedes Tuners

Supercharged 2004 C230 Gets a Performance Upgrade by Mercedes Tuners

Today’s Mercedes Tuners tuning story is about the 2004 Mercedes Benz C230 Kompressor Sport. Mercedes Kompressor, which could perhaps be mistaken as an autobot in the latest Transformers movie. It is really just a fancy term for supercharger. A supercharger is used to boost car’s power and speed by mechanically increasing the intake of air. Indeed, the first supercharged cars came from Daimler-Benz in 1920s. With the experience gained from supercharging aircraft after WWI, the first supercharged Mercedes were unveiled at the Berlin Auto Show in 1921. They certainly caused a bit of a stir. At the Targa Florio race in 1922, a supercharged Mercedes would kick off a long series of wins for Mercedes and Mercedes-Benz racing cars.

To begin with, those very early supercharged models can be best described like this: “To drive them, to hear the shriek of the mechanical charger, to feel the power of its engine, to enjoy the luxury of the refined ambiance or to compete in racing… that was clearly the crowning glory of motoring.” Today, supercharged Mercedes look a lot different than their predecessors, but that sentiment and passion remains. Additionally, we also use the power of tuning to make this C230’s engine perform to its greatest potential.

Why Mercedes Tuners Love the Supercharged 2004 C230 Performance Upgrade

The exterior styling of the C-Class was inspired by its big brother, the S-Class. Our Mercedes Tune, a Stage 1 tune would increase horsepower to 227 and torque to 231 LBS-FT.  Of course, that’s a nice boost for this car. No matter what model Mercedes you drive, we will customize your tune to you. You can even keep your old stock tune with a ECU+ package. Although we rarely see people go back to stock.

Ultimately, we take pride in optimizing the engines for improved performance and fuel efficiency. Equally important, in this case, we analyzed and adjusted this C230’s electronic control unit (ECU). As a matter of fact, Mercedes Tuners tailor the programming to provide more power and torque. Furthermore, other tunes based on your specific needs are also accommodated.

The Results

Our customers typically report back a reduction in fuel consumption, a smoother acceleration and a much-improved throttle response. We are always careful to provide the best possible performance and results, within the original safety margins of your car. If for some reason the tune seems too powerful for everyday driving, we can easily modify your tune or return it to its stock file.

Most importantly, we have spent nearly 30 years maintaining Mercedes Benz vehicles from complete rebuilds to Mercedes ECU tunes. Indeed, during the past 10-15 years, cars have been getting a lot more complicated. Much is controlled by the likes of the ECU that you can really make a difference without expensive upgrades.

Mercedes ESL Replacement on a Mercedes C Class W204 Chassis Have A Bad Mercedes ESL or Mercedes EIS? We Have a Permanent Fix for That

As obsessed as we are with all things Mercedes, we are the first to acknowledge. When we see something that’s not quite right. Today we’re talking about part of the Mercedes EIS being a faulty electronic steering locks (Mercedes ESL Replacement), and an inexpensive way to fix them. “Why? you might ask. If you have a Mercedes C Class W204 chassis you’ve probably already felt the pain of a bad steering lock and it’s just waiting to happen again so you need a Mercedes ESL Replacement or Mercedes EIS programmed.

History of the Mercedes EIS

Mercedes EIS (electronic Ignition Systems) have been using electric steering locks since 1998. On the C-Class, E-Class (up to 2009), the CLK and some later SLK models. It wasn’t until the Mercedes C Class W204 steering lock that owners started noticing issues. An electronic steering lock should be an innocuous thing– meant to irritate would-be thieves and not you. But unfortunately, it appears that the Mercedes C Class W204 chassis lock in particular was poorly designed, and we’ve seen hundreds of reports of them going out all the time, and even folks needing to replace them multiple times over. That’s when you need a Mercedes ESL Replacement.

Owners have complained of their engines failing to start when they try to turn the key fob in their vehicle’s ignition. The car’s electronics, like radio and lights, turn on, but frustratingly, the engine fails to crank. It points directly to the Mercedes EIS. Most common in the Mercedes C Class W204. We’ve also seen this faulty steering lock on the Mercedes E Class Coupe with the W207 chassis. Not as frequently but still we come back to the Mercedes ESL Replacement.

What is typical in the Mercedes C Class W204? First when you insert your remote key in the EIS switch (Mercedes EIS or EZS), it must be recognized by the Mercedes EIS and the ESL. Only then will the EIS unlock the steering shaft, the ignition will switch on and the car will successfully start. If the ESL does not unlock the steering shaft, your car maddeningly won’t start. Owners and mechanics alike, loathe this steering lock. Due to the nature of the EIS this can be quite costly to repair at the dealer. Luckily that’s not your only option.

The Solution?

We have a solution at PRESSERtech to provide a permanent repair. A Mercedes ESL Replacement that you only need to do it once. You’ll never have to worry about the next time your Mercedes C Class W204 steering lock fails. What we can do is replace the steering lock with an emulator (see picture below). It bolts into the exact location as the lock, but doesn’t actually have any moving parts to fail. Now the car thinks it has a steering lock because it is programmed the same as a regular steering lock. But voila, no more worries about malfunctioning ESLs on your Mercedes C Class W204.

But how does that actually work? You will remove a faulty steering lock by first removing the steering column. This includes the steering lock’s bolt. We need to collect the faulty steering locks as a core. We can remove the steering lock from the column for you if you would like. This will be a small additional cost and you will need to provide us with the entire column. First have your local mechanic give us a call and get your Mercedes ESL Replacement and this permanent fix to this faulty C Class W204 steering lock.
