Even though this is my S600, I am posting this over here for you S65 guys as Eurocharged can also do the same for you

Okay guys, I finally made the decision to have my beast tuned. I was torn between a few tuners, and decided to go with Eurocharged. After spending this past weekend in Chicago, I can only say, THANK GOD I DID THIS.

I arrived at Eurocharged around 9:00 am Saturday morning where Jerry was busy tuning his new toy, a 135. After about half a dozen pulls, he rolled her off and on went the S600. We did a few base lines pulls and were rewarded with an average of 370 RWHP, and 505RWT. Note: Eurocharged’s Dyno is known as the “Heartbreak King” aka Dyno dynamics load bearing style.

Jerry asked me what I was looking for, and I informed him that it needed to be a daily driver, aka wife friendly, and that I was only looking for a 50 RWHP and 80 RWT gain. I was also concerned with leaning out the mixture, which Jerry assured me he wasn’t going to be doing anyway. My concerns about timing and mixture were quickly put away when Jerry had me watch his A/F monitor on each and every pull. Thanks Jerry for easing my mind.

On the very first pull with the NEW tune, I was rewarded with a 100 RWT and 45 RWHP GAIN. WOW, this was going to be a GREAT day for my car.

After making a few minor adjustments, the numbers stayed about the same, give or take and I was willing to call it quits for the day and head out for a night on the town as I was already TRULY satisfied with his results. Luckily, the wife called and was delayed downtown, so I gave the Jerry the heads up for more. AND BOY DID I GET MORE! At the end of the day, I picked up OVER 170 RWT, and almost 60 RWHP.

When all was said and done, we made 17 pulls on the dyno. I know not for the faint of heart, but Jerry was committed to my project and I had the time so why not. Jerry took the time to make sure that not only did I get what I was after, , but that the tune was safe, reliable and repeatable.

Dyno's are attached for your enjoyment

Bottom line is that their tune exceeded ALL my expectations. On the drive home my mileage remained the same, 20.1 on the way out, and 19.8 on the way home with a few more local stops. The car is simply AMAZING off the line and part throttle passes on the freeway. The car tends to downshift a lot less now as there is MORE power across the entire board. Playing now is truly an event, with power sliding sideways on the freeway ramps at will. Heck, she even got loose on me in the top of second on one straight line pass, which is an event that has NEVER occurred before. The wife summed upped my weekend experience the best with this statement, “You better buy some stock in a tire company soon, as the rear tires will need replaced bi-weekly”.

THANKS Eurocharged and a HUGE THANKS to Jerry for spending the time with me to satisfy all of my questions and desires with my car. If ANY of you are thinking about tuning your car, I would HIGHLY recommend giving Eurocharged a call first. You will NOT be disappointed with their above and beyond customer dedication approach.

PS: They now have the STAR diagnostic tool, which they used to lower my car as an added bonus!! Beats the heck out of using washers or those ridiculously priced arms for a simple drop, and sure was fast and easy.

congratz on a great tune!

supper happy for you!

 

Congrats and great write up!

 

nice I really wish they would consider doing that socal event again. I really don't want to do the remote tune

 

Here are the graphs of the 2009 S600 that we had on the dyno today....what a beautiful car.

Not as impressive as the W220 and much harded to tune IMO. It's amazing what cold IC's can do!

Pink is hot run
Blue is stock
Green is ice / cool down for 30 minutes

Enjoy!

 

That's great story.

Hard to believe you were getting only 375 BHP at the rear wheel since this is 30% loss, people usually talk about 10-20% loss from flywheel to rear wheels.

How noticeable is the additional power and torque in your daily driving? Do you fell it all over the RPM range or mostly higher end of the RPM range?

Thanks.

 

As I mentioned above. The car does not downshift nearly as much anymore. Passing power is unreal now with just a touch of the throttle.

Just drove her to work today, outside temp was only 46. On my local on ramp, I was into the back of a truck in about 4 seconds

This power is truely fantastic in the cold It has surprised me once or twice with how much torque trying to go sideways at 50-60 mph.

Thanks again Jerry
