**~**Powerchip Performance Tuning! Easily & safely gain HP/TQ!**~**
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.

Chip purchased: January, 2006

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

Customer comments:
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)

Customer comments:
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.

The dyno sheet I posted was one I had on hand, not one of our best runs, just an example of how the powerband is increased.
Trending Topics
The Best of Mercedes & AMG
Also, I had posted that graph early this morning, along with a few others I had on my laptop. It's Saturday and I'm working from home, therefore do not have access to our server and other dyno sheets; Otherwise I would post them.

I hope that explains it.
It may be to your advantage to dyno the stock car on a hot day and then tune it on a colder one to show more of a gain. Am i wrong on this but doesnt the dyno machines have temperature variation system of some sort.
I couldnt see this not existing for dyno machines as every tuner would take advantage

Again some of the cars have exhaust systems its on you charts. Come on that means the stock is no mods and second run is with software and exhuast its clearly on your paperwork.

Tuning a car for 93 octane fuel provides much better gains than 91 but unfortunately the C55 in the dyno was tuned for 91 octane fuel, not 93; hence the lower #'s. Since something like 48 states have 93 octane fuel, the 93 octane numbers are most commonly listed.

If you have any further questions or would like a datasheet for your vehicle that includes more info feel free to shoot me an email or pm.
Would love to get the chiptorque tune in Australia for $690 USD. Do you have a tune for a C32 with Evo pullies? What kind of gain is expected?
Theres a place in australia that tues our cars but the price is costly and the gains are questionable.
do you tune your car with chiptorque?
For all who want a Powerchip data-sheet which includes a dyno graph feel free to shoot me an email to Aaron(at)StealthAuto.com.
