Hello Everyone!

We are currently offering our M278 biturbo tuning on sale for $1499! plus shipping!

Unleash the true power of your new Bi-Turbo Mercedes with Eurocharged Tuning!

We first read the existing software off of the car with our specialized software and hardware. Then our expert tuners apply our performance and drivability changes to your existing file, and flash it back to the car!



Our M278 tune is very safe, and has been extensively road and dyno tested. To improve the already powerful mercedes engine, we completely disassembled the code of the ECU. The end result is more power and torque, resulting in better acceleration, better shift performance and better drivability. We also modify the vehicles timing, adjust the fuel maps, and change some of the engine management on the car to maximize the end product.

Eurocharged has one of the best warranties in the business, including a motor replacement warranty should our software cause any issues!

How does your upgrade work? Do you send a new ECU or upgrade existing one and ship it back? Kindly provide more details. I have a 2007 S65 AMG. Thanks.

you would ship your existing ecu, we would load our software for you, and ship it back next day air.

I looked at your website. Do you recommend ECU, TCU and cooling system upgrades all at the same time? Also, how many of these have you done for the V12TT engine (2007 S65) and what is the reliability history?

Much thanks.
