I found this information on the web:

Original 231ps/540Nm
DTUK.uk 280ps/660Nm - 464€ - Multi chanel tuning box
Kleenann 290ps/650Nm - 675€ - connecting only to the rail
Chipexpress.com 282ps/702Nm - 525€ -
DigitalTuning.ch 261ps/631Nm - 570€ in Bulgaria - ECU remap via OBD (but no warranty problems in Mercedes service, DigitalTuning guarantee)


But I'm little confused. I'm wondering which one to choose, and which one is more important: more horse power(ps) or more torqude(Nm) ?
Can somebody give me an advice.

I always understood more torque for faster starts from a stop and more horsepower for quicker acceleration once you are moving. This is why big trucks have thousands of pounds of torque but only 500 plus horsepower.

I could be wrong though

Thanks for info
I ordered one from Speed-buster.de. Will test their product with Dyno.
And will upload some pictures, video and results.
I wonder whether to put a sport filter K&N?
Does anyone know if the air filter of the coupe is like a sedan?
I ask becouse in my engine original filter is glued to the top of the air box lid - they are one piece! I found these product 33-2940 in K&N site, but the picture therе is different!
Аnyone have more information?

i'm not seeing on your list any good options.i think you should check on BRABUS,CARLSSON or LORINSER.They are though tuners for the mercedes.they will give you a real waranty.

the sport filters won,t give you any power.only a bit of sport sound but in your diesel case i don,t think it will make a difference.

That was a comparing test for "multy chanel chiptuning box", but the results were disappointing, that's why I returned it.

The results form my Dyno run:
Serie/ Factory: 224 ps / 531Nm
With the "box": 232 ps / 582Nm (only 3.5% ps and 9.6% Nm)
The Speed-Buster.de promise in 25% Ps and 15% Nm ( announced: 289Ps and 621Nm).
Fuel consumption increase by almost 3 liters / 100 km

In the graph is green line is Factory, and the red is with box.

Did you try adjusting the dial? it has 0 to 9 .... which setting were you using?

I can highly recommend the DTUK system. Great customer service and backup. Whatever system you buy make sure it's multichannel (fuel and boost) fuel only is asking for either too much smoke or overloading of the particualate filter if fitted.

Don't shop by power numbers alone, smoothness is much more important, if it's got crap drivability then you'll hate it no matter what power you can get out of it!

Double check if your engine is the 540NM or the later 620NM engine, they will need different maps in the tuning boxes depending which engine you have. make sure you order the right one.

I am trying out TMC chip tune right now but I am hearing that they are rebadged speed-buster.

Your dyno show pretty poor gains from that.... thats why i was wondering what setting did use when you dyno'd it?

also after getting DTUK did you dyno again for comparison? Please elaborate ur experience.....

I do have the revised engine which makes 241 HP and 455 torque.
