StealthAuto

Hello forum members!!! I'm pleased to announce that Stealth Auto is now a forum sponsor and will be retailing Powerchip performance software. Powerchip is a European tuning company that has been tuning these vehicles for the past 15 years.

Just to give you a brief summation of how Mercedes tunes their vehicles... All MBZ vehicles are tuned very conservative from the factory. They do this because they're afraid of "the wife" or non-car enthusiast putting lesser octane fuel in and possibly damaging the car. Also, some states like California have 91 octane fuel at best which severly limits how aggressive tunes can be from the factory.

By simply tuning your car for the premium fuel in your area (most likely 93), you will see amazing power gains in addition to slightly increased mileage per gallon. Your car will in essence be set for a particular octane fuel and will in return recognize that fuel and act accordingly; something it could not do with the absence of our tune. Another key benefit of our tune is that we can adjust your throttle response which greatly improves day-to-day driving. For example, if you push your pedal down 25% our tune can actually make that 35-40% (not in exact #'s). Increased throttle response will eliminate dead spots in the lower rpms. Lastly, your car will see increased mileage per gallon due to it running more efficent with our software. (This does not apply to you lead-footed people who are going to exploit your newly found power )

Powerchip can individually tailor your tune for exhaust, intakes, etc.. We've had so many happy Mercedes customers over the past 10+ years that we're content in offering a 14-day money back guarantee.

Please find a few Mercedes vehicles listed below along with the fantastic gains they can see with our 93-octane tune.
S500 - +27hp +30tq.
C55 - +25hp +26tq.
CL500 - +27hp +30tq.
CL600(twin turbo) - +98hp +103tq.
CL55 - +24hp +27tq.
CLK500 - +24hp +27tq.
E500 - +21hp 23tq.
E55K - +30hp +35tq.
ML500 - +28hp +26tq.
SL500 - +27hp +30tq.

Customer comments:
The CLK350 is quite fast from factory for its class, but after Powerchip upgraded my ECU, it's significantly better. Better throttle response, same gas mileage, OEM reliability. Before the upgrade, I could slightly break my back tires loose with ESP off, but after the upgrade, I could spin them freely with ESP off. Thanks for the great work Matt & your team. I would not let other tuners to touch my ECU but Powerchip down the the road.

Customer comments:
I noticed the increase in pick-up off the line and the mid range acceleration right away! It seems to have much more pulling power without having to slam on the gas pedal. I am very pleased with the results and recommend Powerchip to anyone else that's looking for that extra push!
Also the over night ECU shipping made this whole process a breeze...
Great power upgrade for the buck!

I can't believe this works...i just shipped my chip overnight to LA and the following day, I installed it back into my car. Now its just such a fun car to drive. I like to rev it all the way and take advantage of the new rev limit. And the other good thing is, now I can reach my cars maximum speed without it cutting out and hitting the 'speed wall'. Overall, great product, and thanks for the customer service as well...I'll be sure to tell my friends about you guys

My 2nd Powerchip...first one was for my 1995 MB C36 AMG...I loved the difference and I sold it to a friend who continues to run it with no problems, 120,000 miles and nearly 300 bhp. My wife drives our new E320 most of the time and when I snuck the Powerchip into it within a month she asked me, "Did you put a supercharger in this?" No lie, she even felt the difference. Along with my dual K&N Air filters and REMUS Cat-back sport exhaust I went from 221 bhp to 252 bhp, off the line is fantastic with 258 lb/ft of torque. I have the E320 that MB will release in 2004 or 2005 when they upgrade the power, I have it already today. Wayne B. is awesome. Thanks Wayne. response.Write(imgname)

Having used Powerchip for my previous car a CLK430 and now an E55 the difference is noticable from launch to the rev limit - the car is more responsive and changes down quicker for overtaking where it counts - It certainly feels quicker - though I recommend switching the traction control off first!
In respect to long distant fuel ecconomy it's still to early to tell - though due to the kw & Nm hike I would suspect a better result at crusing speed.
Thanks Ryan & Mark

The car is more responsive...no doubt. I feel the increase in torque and horsepower. The customer service was excellent and the turnaround time was two days as promised. The car is just a more fun car to drive. Thanks.

Please find a few dyno graphs below as well as some images and videos. Please excuse the fact that some were taken on a camera phone, I did not bring a camera to most dyno sessions.

how about clk 320, 2001.

StealthAuto

A 2001 CLK320 will gain 20+hp and 25+tq. The cost is $690.

I sent you a pm.

arthurx01

gotcha, just wanted to get some pricesand info.. thanks!

StealthAuto

No problem at all bro.. I'm always glad to help.

sick430

is it just the ecu or all so the tcu and do you remove the speed limiter. thanks

MadHorseDisease

Is your tune an ECU flash or is it something I can "turn off and on" at will?

Also, does it come with a warranty and / or live tech support for DIY's?

Thanks.

P.S. Can you send me some additional info for my car too? Thanks again!

StealthAuto

We only tune the ECU, which allows us to - aside from gain horesepower - adjust the throttle response and remove the top-speed limiter.


Our tune is an ECU flash. We backup your stock software just incase you ever want to go back to stock. Since our tune safely improves hp/tq, throttle response and gas mileage there's no negativity to having it loaded 24/7.

In regards to warranty, all of Powerchip's software has a 3 year warranty which can be extended for a nominal anytime within the first 3 years. Since software never changes there's really nothing to worry.

Aside from the warranty Powerchip offers a 14-day money back guarantee to ensure you're happy with your purchase. Basically they make it so you can't go wrong.

I sent you a PM regarding your car.

jtbeche

Correct me if I'm wrong, but the removing the top speed limiter won't work on the 98-99 models, will it?

StealthAuto

You're correct.

CLK43kaz

how bout for a CLK430 2002

Traildust

I am very pleased with the change in performance on my 430! I did not have my car Dyno'd, but I can feel a wonderful boost all through the throttle range. I just reinstalled the ECU yesterday and have driven for about 100 miles. The gas mileage does not seen any different, but the torque and power are!

For the money, this is a great mod! I highly suggest these guys.
