Client Review: Stage 2 Tune Takes AMG GTS Restrained to Maniacal Demon

Client Review: Stage 2 Tune Takes AMG GTS Restrained to Maniacal Demon

PRESSERtech Client Review: Stage 2 Takes AMG GTS from “Restrained” to “Maniacal Demon”

We love hearing stories from you about your performance tuning journey. Today we’re thrilled to share a Stage 2 tune review from our client Larry Flaxman. Larry recently fell in love with a 2016 Mercedes AMG GTS Edition, but found that it didn’t have quite the bite he was expecting. With two very important goals ahead of him (“more horsepower and more loud”), Larry dove into the world of Mercedes performance tuning, and we were lucky enough to get to work with him.

Strap in to read about Larry’s experience with PRESSERtech and his review of this Stage 2 tune, which turned his civilized and restrained AMG GTS into a “maniacal demon.”

Like Father Like Son, A Passion for Mercedes Benz

Ever since I can remember, automobiles have played a significant role in my life. My Dad was an avid auto enthusiast – owning a variety of cool and often unusual vehicles. Mazda’s, Toyota’s, Lincoln’s, Infiniti’s, Fiat’s, and Mercedes.

Of his cars, two have stuck in my memory: a 1977 Mercedes 240D, and a 1978 Mercedes 300D.

Those two diesels sedans were his pride and joy. I can remember many a time seeing my Dad outside lovingly washing and waxing them both at all hours of the night… even when he had followed the exact same routine only a few days prior. To some, owning two Mercedes likely represented extreme hedonism and outright showmanship, but, to my father, they symbolized much more. They were his passion. A passion that made a significant and lasting impact on me.

Hi, my name is Larry.  I’m a best-selling author and tv personality (www.LarryFlaxman.com) that would self-identify as a car connoisseur.  Over the course of my “adult” life, I’ve bought, modded, traded, and sold more cars than I can possibly recall. I use the term “adult” figuratively because, well, do any of us truly ever grow up? That old saying about boys and their toys is amazingly accurate.

I’ve been fortunate to have owned just about every major marquee imaginable – BMW, Porsche, Toyota, Mitsubishi, Nissan, Ferrari and Lamborghini. Surprisingly, the Mercedes brand had been missing from my ownership portfolio.

Until last year.

Love at First Sight: 2016 Mercedes AMG GTS Edition

One day while browsing cars on eBay, I came across a new 2016 Mercedes AMG GTS Edition One being offered by a MB dealer in California. I had honestly never heard of this model, let alone seen nor driven one… yet I instantly fell in love. It was utterly mesmerizing with absolutely gorgeous lines and coachwork reminiscent of early 50’s style racers. I had to have it.

After some back and forth negotiation (and what felt like endless back and forth paperwork), I traded my heavily modified 2008 Lamborghini Gallardo Superleggera for it. Next step was the long, impatient wait  for the cross country enclosed transport to drop off its wondrous cargo (and pick up my own pride and joy.)

On the day of it’s arrival,  I felt a flashback to senior year of high school prom. I was so nervous and scared… yet incredibly excited. I could barely contain myself! Oh wait… never mind, I didn’t go to my senior prom.

Anyways, as the driver backed my new Selenite Gray chariot down the ramp and proceeded to pull the Lambo in its place, I shed a tear. A tear of both joy and sadness. Would this new toy fulfill my need for speed? Would it sound good? Would it impress the ladies?

I had watched a few YouTube video reviews of my new car… but, honestly, that was the extent of my pre-purchase research. Upon finally seeing the car in person, my first thought was “holy crap, it’s so much larger than I thought!”

Something’s Amiss: An Engine that’s Too Quiet, Too Refined

My second thought was – “wow, it’s so quiet.” Too quiet.  On my first drive I figured out that I could adjust various parameters such as controlling shift points, exhaust tone, and suspension firmness.

But the sound. Even putting the car into Sport+ mode didn’t quite satisfy me like the sound of my yellow screaming V10 (with Fabspeed pipes, intake, etc.) When downshifting, the Lamborghini grunted, barked, and popped. It was truly a glorious symphony and announced my presence several blocks before I would arrive at my destination.

Sure, the Merc was fast… deceptively so… but, it was also sophisticated and refined. In fact, it was way more refined than any other car I’ve ever owned. The GTS is a remarkable vehicle both stylistically and technologically, but, I felt so disconnected from the overall driving experience.

My wife joked that I had finally upgraded to a “grown-ups” car. Truth be told though, I wished it was rougher. I missed the visceral, “sports car” feel I was so accustomed to. Beyond the remarkable Lamborghini sound, I also missed that “oh sh*t” feeling of my neck nearly snapping due to violently being thrown back against the seat when I dropped the hammer.

I’ve been around high performance cars long enough to recognize that this new whip likely had significant hidden potential lurking within. She simply needed some help to achieve excellence.

Was I up to the task?

Delving into the Mercedes Performance Tuning World

In an effort to educate myself, I joined a several MB message forums and Facebook groups to begin my journey into understanding the Mercedes universe. Coming from an incredibly active Lambo and Ferrari world, I was hopeful that Mercedes owners would be equally as helpful and patient with a newbie such as me. Likely due to the “newness” of the GTS, I didn’t find much specific mod info… however, since it utilized the M178 engine there were definitely some solid suggestions available.

After a few weeks I had outlined a plan to transform my car. My two primary goals were more horsepower… and more loud.

I immediately set about having the secondary cats removed (weight reduction and airflow) and adding high flow air filters and airbox spacers. Supposedly, these mods should be good for 30-40hp.

Short of a full cat-back exhaust, upgraded turbos, or other significant engine work, the biggest impact would likely come from an ECU tune. In previous cars I’ve always done ECU/TCU tunes when possible. Throughout the years, I’ve used many of the major aftermarket tuning companies with varied levels of success. Some were fantastic… and some were simply mediocre at best.

A search of the forums yielded little tangible info, but, tons of personal opinions. Now, opinions are great, but, if I’m going to spend $2k+ for a tune, I want to do my due diligence and ensure that the numbers are there to back up the opinion.

Which Mercedes ECU Tune Company?

Being the incessant Mercedes newb, I posted on one popular message forum asking for opinions regarding the tunes from a few companies which were known to be the heavy hitters in the Mercedes ECU tuning world. From my research, I had narrowed my choice down to two companies: Eurocharged Performance in Houston, Texas, or Pressertech in Atlanta, GA. I simply wanted some input regarding pros and cons of each. At first, there were quite a few helpful replies, but it quickly degraded into a massive non-productive, finger pointing, drama infested mess.

No thanks to the folks on the forum espousing every doom and gloom scenario possible if I were to choose a tune from any company that cost less than a Bugatti payment, I was now significantly scared enough that I said, “screw it” and wrote off Mercedes ECU tuning as a liability.

I continued to enjoy the car, but, secretly pined for better performance. While attending car meets and shows, I often found myself feeling pangs of jealousy when a Porsche, BMW M series, or Lambo pulled in. While my AMG GTS certainly attracted attention, the actual driving experience still felt too civilized and restrained. My wife was right – and I hated it.

Five Star Communication with PRESSERtech

Several months went by, and honestly, I had forgotten about my tuning journey until I received an email from Todd Presser, CTO of Pressertech. He reached out to ask if I had chosen a tune yet and I told him that I had not.

After explaining my artificially induced hesitation, Todd allayed all of my concerns. It turns out that only a few companies actually produce tunes for these cars… which means that most of the base tunes (even from the big-name players) are exactly the same with only minor differences applied by the individual company!

We discussed options and expectations. I was very adamant about my requirements. I wanted to ensure the tune would not only significantly increase horsepower above and beyond the stock 503hp, but also would not negatively affect long-term reliability or usability of the vehicle. Oh… and sound. I wanted more loud.

Todd patiently answered all of questions and assured me that if I wasn’t happy they would do whatever was necessary to satisfy me.

After our nearly hour-long conversation, I decided to pull the trigger on their stage 2 tune (605hp and 625LbFt torque.) With my existing mods that should put my car close to 650hp. I’ll take that.

My ECU was in the mail that afternoon.

From the moment it arrived at Pressertech until it left for its return journey home, Todd continued to update me regularly. In today’s often impersonal, disconnected world, Pressertech’s communication was refreshing and definitely worthy of five stars!

Four days later the ECU was back in my hands. I quickly went about reinstalling it, however, torrential rain relegated the first startup to be in the garage.

Wow. It certainly sounded louder, but, it was in my garage, so, I’m going to chalk that up to simply being my imagination.

The True Test: From Civilized to Downright Brutal Performance

The next day I got up early to take her out for the first proper shakedown cruise.

Pulling out of my neighborhood in eco mode, I felt slightly disappointed as the car didn’t seem to have been magically transformed as I had hoped. In fact, if anything it seemed quieter and even more refined. Ugh. Were the forum guys right? Was this whole experience an exercise in futility? Would I ever get my passion back?

Maybe the car simply needed some time to adapt to the new software?

Then I dropped into Sport+ mode. HOLY HELL! Instantly, the car came alive. I hit the fun pedal and literally could not wipe the grin off my face.

Excitement & Passion of the Mercedes AMG GTS Edition

30 minutes quickly turned into 60, then 90 while cruising around with no destination in mind… Time seemed to completely escape me in my “new” car. I felt that sense of excitement and passion that I thought was long gone.

Upshifts and downshifts were more purposeful and deliberate. The car accelerated like a speeding freight train… pulling harder and harder, faster and faster all the way up to redline. Actually, brutal would be the best way to describe it. Stomp the pedal and you are instantly pitched back in your seat like a limp rag doll.

And the sound. Oh my! The sound emanating from the pipes took on a much more aggressive, deep tone. Granted, this isn’t my daily driver, so, perhaps I simply forgot how awesome it sounded before?

Nope.

The tune definitely changed something – whether fuel or air mapping I can’t say, but, the sound of the car now closely approximates an angry hell beast in full attack mode. At full throttle the sound is absolutely glorious.

As I downshifted and slowed towards an approaching stop light, I instantly heard something else. Something familiar sounding, yet so foreign. The growl, pops and burbles were back! I had resolved to accept the fact that those sweet sounds were forever gone when the transport truck pulled away taking my Lambo with it..

Nope.

Not only is the car significantly faster – whether from a roll or full stop, the sound is noticeably more sports car like. I finally knew that I had made the right decision in trading for the GTS.

A Stage 2 Tune Transformation from “Grown Up” to “Maniacal Demon”

While I don’t believe in sorcery or black magic, whatever wizardry or pixie dust Todd and Pressertech have up their sleeves are simply amazing. This thing is an absolute beast now thanks to them. There are so many appropriate words that now describe my car: mystical, supernatural, ethereal, wonderful… but I think EPIC would be the best.

To say I am pleasantly surprised would be the biggest understatement of the year. Not only did the Pressertech stage 2 tune wake up the vehicle, but, it literally transformed my “grown up” car into a maniacal demon at full boil. Mercedes – if you are listening, this is absolutely how the car should have come from the factory.

If you are interested in upping your game and taking your car to the next level, you absolutely owe it to yourself to check out Pressertech.

“I couldn’t find the sports car of my dreams, so I built it myself.” – Ferdinand Porsche

2016 Mercedes C-Class Tune Mercedes C300 W205 Tuning – Unlocking Hidden Potential

The Mercedes C-Class Tune (Mercedes C300) is based on a line of compact executive cars, playfully described as having “as many flavors as a fro-yo shop.” The Mercedes C-Class features four body styles — the sedan, wagon, coupe and cabriolet. Mercedes C-Class are built in Mercedes factories in Sindelfingen and Bremen, Germany. The series looks to emulate its big brother, the Mercedes S-Class, but on a smaller scale.

The 2016 model comes with standard rear wheel drive and delivers 241 horsepower and 273 LB-FT of torque. All this comes from a turbocharged 2.0-liter 4-cylinder engine.The W205 is the first to use the Modular Rear-wheel drive Architecture (MRA) platform, using a significantly lighter aluminum structure. Having said that, this stock Mercedes C300 Tune has many things going for it, but we know we can unlock the hidden potential of this vehicle. Despite the fact that so many other Mercedes models have an aggressive nature, this engine was depowered at the factory, and just yearns to be set free. That’s where we come in.

Mercedes C43 AMG v Mercedes C63 AMG Performance Tune

Mercedes C43 AMG v Mercedes C63 AMG Performance Tune

Mercedes C43 AMG Performance Tune – Huge Gains All Around 

At Pressertech, we recently wrote about tuning the Mercedes C63 AMG — the “iron fist in an iron glove” — and how we were able to provide a 19% increase in horsepower and a 27% increase in torque with a Stage 2 tune. Today we’re looking at the C63’s little brother, the Mercedes C43 AMG Performance Tune. It’s been described as “balanced, competent, and just powerful enough to be exciting.”

Mercedes C43 AMG vs. Mercedes C63 AMG

The Mercedes C43 AMG sits in the Mercedes lineup between the Mercedes C63 AMG and the C300 coupe, making it an appealing middle ground between the two models. Instead of a V8, the Mercedes C43 AMG has a twin-turbo V6 (“one of the best sounding V6 engines out there”).The standard 4MATIC all-wheel drive makes for a ride that won’t drift as easy. It boasts balanced and composed suspension, and an overall better ride quality than the Mercedes C63 AMG. Tested on the autobahn, the Mercedes C43 AMG proved to be solid and confident, even at speeds upwards of 140 mph.

Mercedes C43 AMG Specs

At stock specs, the Mercedes C43 AMG brings 362 horsepower and 384 LBS-FT torque to the table. It’s a distinct upgrade in performance from the C300 coupe. At PRESSERtech, we have the ability to upgrade the C43 AMG to two levels through our comprehensive Mercedes Performance Tune. A Stage 1 Tune would bring this coupe to 403 horsepower & 441 LBS-FT torque. For even more power, a Stage 2 Tune would bring the C43 AMG to 413 horsepower and 464 LBS-FT torque. That is just amazing!

Mercedes C43 AMG Performance Tune Process

Mercedes Performance Tunes are a great way to boost the capability of your vehicle without having to replace any stock components. It’s a cost effective way to get more power out of the car you already own and love.

When tuning the C43 AMG, our expert technicians targeted the car’s engine control unit (ECU). After removing the ECU with extreme caution, we use our in-house technology to modify its stock settings. By modifying the ECU, we’re able to unlock the true potential of your vehicle’s engine. We’ll also keep your original Mercedes flash tune on file, so there should be no fear of trying out a tune on your car. If the tune isn’t to your liking, we can always modify it or change it back.

Mercedes C63 AMG Performance Results

When we tune a Mercedes, we see better throttle response, increased efficiency through all loads and gains all around. For this Mercedes C43 AMG Coupe, a Stage 2 Tune provided a stunning boost of 51 more horsepower and 80 more LBS-FT torque. That’s a 14% increase in horsepower and a 20% increase in torque. It’s incredible to see what kind of performance upgrade can be achieved simply through tweaks to a car’s ECU, without making other expensive upgrades and being perfectly safe with all stock components.

Mercedes C63s AMG Stage 1 Tune Stage 2 Tune

Mercedes C63s AMG Stage 1 Tune Stage 2 Tune

2018 Mercedes C63s AMG Staggering Stage 1 Tune and Stage 2 Tune Results

Mercedes C63s AMG: As we look towards the Christmas holiday, we’re thankful for time with our family and friends. We’re also thankful for the opportunity to get to do the work that we’re passionate about… Performance tuning Mercedes, Audi and BMW vehicles. We recently got to tune a 2018 Mercedes Benz C63s AMG. It’s a car that was once described as “an iron fist in an iron glove, it’s just brutal.” Not only did we see this brutal power with the Stage 1 Tune, we saw the staggering upgrade with the Stage 2 Tune.

AMG Means Serious Business

For a bit of trivia, AMG stands for the names of the founders and the town where they first set up shop: Aufrecht Melcher Großapach. AMG is celebrating its 50th anniversary this year. It’s also their 18th year as a Mercedes Benz subsidiary. Their mission is to elevate the performance of Mercedes vehicles, and we’re always excited to take that mindset a step further.

Mercedes C63s AMG Stock Specs

The Mercedes C63s AMG has M177 4.0-liter V8 biturbo engine, similar to the AMG GT sports car. It jumps off the line, charging from 0 to 60 in 4.0 seconds. At stock, this car performs at 503 horsepower and 516 LBS-FT torque. We couldn’t wait to see what kind of power could be unlocked for this car when we gave it a Stage 1 tune and then a Stage 2 Tune.

Mercedes C63s AMG Stage 1, Stage 2 Tunes

For this C63s AMG, a Stage 1 Tune would up performance to 570 horsepower and 600 LBS-FT torque. Further, a Stage 2 Tune would really make our eyeballs pop out of our heads, with an anticipated 600 horsepower and 660 LBS-FT torque.

The Mercedes C63s AMG Stage 1 Tune and Stage 2 Tune Process

In fact, when our expert technicians’ tune, they target a critical piece of technology under the car’s hood. That’s the engine control unit or ECU. Tuning is a complex process and the ECU needs to be handled with care. When we removed the Mercedes C63s ECU, we used our in-house technology to modify its settings, unlocking this vehicle’s potential. Watch Todd at work on this C63 S in this YouTube video.

Of course, that’s one of the reasons we love Mercedes is that we can do a Stage 2 Tune without having to replace any stock components and still be able to pull off some crazy performance numbers. This is because Mercedes already uses such great components and their cooling systems are on point. We have a really solid foundation to work from.

Mercedes C63s AMG Performance Results

Moreover, when we tune a Mercedes, we see better throttle response, increased efficiency through all loads and gains all around. For this Mercedes C63s, this included a boost of 97 more horsepower and 144 more LBS-FT torque. That’s a 19% increase in horsepower and a 27% increase in torque. It’s incredible to see what kind of performance upgrade can be achieved simply through tweaks to a car’s ECU, without making other expensive aftermarket upgrades.
