Seems there are quite a few options, EC, OE, LOGICLAB... I can't decide which is best, EC seems to get more love, but I'd appreciate some more recent feedback, thanks guys!

I wish I could tell you to try one over the other but my motor has not been broken in yet so I have not started the process of mods. EvoII_Racer is running a Vath tune and Nanook is running a Renntech tune. Both of them have been very happy with their choices.
Euro, AMS, Renntech, OE, Vath and a few others have a tune. They all seem to be around the same HP and TQ. I too am undecided but still have some time.

I have a W164, and i am running an OE Tune, and very happy with it.

The below is my opinion:

-I have been tuning all my mb @ Vath and their products are just amazing but you need to be in Europe it's better... Quality/price if upgrade are insane just cf parts are expensive.

-since you are closer to the US I would go with a well know tuner, Renntech because they make incredible products IMO.


You could also chose Brabus or Weistec or even Alpha Performance they seem to offer sick stuff but no direct experience with them even if the look of their upgrade alone are incredible!

ML63 AMG

In the US eurocharged does the highest volume by far. They have more experience than anyone tuning the ECUs, and their newest V4 tune also improves shifting quality as well in the transmission all through the engine ECU tune.

I've had, V1, V3 and V4 so I have felt the progression and I can say they do a fantastic job of tuning methodically. When I get my biturbo ML63 (most likely next year), I will be getting the eurocharged tune.
