I have been told here by one company that sells MB cars that AMG itself is doing ECU retunes for W164 320CDI models. They said power increases up to 264BHP and 585NM. I couldn't sleep very well so I have decided to try and go for it! Car feels much quicker now, I would say it is in Cayenne S territory.

Check it out by yourself.
This is my stock car 0-160KPH (0-102MPH):

My car after ECU retune by AMG:

And finally 60-220KPH - going slightly uphill:

I think difference is quite visible!

 

i only have a petrol car, but how did you get AMG to do it, I have checked everywhere like the 'performance studio' and in the price lists, but all I can see is the increase speed limiters

do u have a link on where to get it done by amg?

 

I do have a link, but it is not in English so therefore it is useless.
I was actually like this , but they said it's really possible.
Maybe you can try to send an e-mail to your local AMG dealership...perhaps?

 

how much did AMG charge u for the tune?

 

It was 1200 EUR.

 

Very cool! Its probably much better than the KD box that I have since MB is doing it themselves

 

I haven't been abble to find any links on the internet, please provide your link, eventhough it's not in english.
I need proof

 

you might try this guy in germany, he is not with amg. I have used him on my audi's. he even flew here in 97 to get the chip from my A8 when they just came out. I tested 4 versions for him. this is european website but i believe he has an office in michigan. frank at wetterauer.de . he thought the kd box was a joke he said it just boosted one parameter to increase fuel rail pressure.

I chipped my '08 ML320 CDI for economy instead of performance. Yes, that is an option if you feel that the vehicle has ample power off the showroom floor, which I did.

The vendor, Paramount Tuning U.K., said that the chip remaps the engine output for perhaps a tiny increase in HP but a much larger output in torque. This allows for downshifts to occur less frequently, and less fuel needing to be used to get the car up to speed and up hills. Check out their website here if you are curious.

I was averaging 27MPG (US) in my ML prior to the chip, and now it's right at 30MPG. That's with about 85% highway and 15% city traffic. I normally travel 2-5MPH over the speed limit, accelerate gently, and coast to a stop if it's obvious the light 1000 feet in front of you is going to be red when you get there (duh). If you can believe I can go almost 800 miles on a single tank of diesel! This vehicle is amazing.

The chip cost me right around $600 so it should pay for itself in about 18 months.

Also see my graph of the history of fuel consumption for my truck. It's clear to see where I installed the chip. Also notice there was a break-in period when I first purchased the vehicle.

 

where did you get it? And will it work on a 09 320 bluetech? I want one!
