Simon Coe at CCC, the Upsolute dealer for the UK can chip it for you.
Mercedes C200 CDI 116 116 hp 145 hp 250 NM 310 NM
Mercedes C200 CDI 122 122 hp 152 hp 270 NM 320 NM
Mercedes C200 Kompressor 163 163 hp 175 hp 240 NM 255 NM
Mercedes C220 CDI 150 150 hp 175 hp 340 NM 395 NM
Mercedes C220cdi 143 143 hp 168 hp 340 NM 395 NM
These figures are taken from the Upsolute website. If yours is the 122bhp they reckon on increasing it to 152bhp:bannana:

Had the DPT device fitted and am thoroughly impressed. It's a very professional-looking piece of kit that tucks away out of sight with the black wiring sleeves merging in with the original fittings. Notional BHP is up from 225 to 270 and NM torque up from 450 to 530 with the range most used in driving noticeably more torquey. Peak BHP can go higher but I'm happy with the present output. Too soon to comment on mpg but looking good despite plundering the new power curve.
Am told DPT leaves peak turbo pressures alone but the common rail pressure sensor data is 'freaked' to raise torque output right along the length of the curve, finessing it towards the top end so as not to overstress the engine components.
I've seen Brabus aftermarket digital power boosters marketed at my franchised dealership so I'm confident this is the right way to go!

These plug-in boxes just raise fuel pressure and risk damaging injection pump and such as well as the particulate filter. A good remap is always best as all the "safety" maps still function. Have a look at this

CUBAN, for me the issue is whether reputable engineering companies use and recommend it. If a product is TÜV certified and adopted by a number of franchised Mercedes-Benz dealers I am reasonably content to exercise my personal judgement. I may be wrong, but then I can afford to be. I back enterprise and sometimes, well, we all make mistakes.
I don't think this is one of them but if it is, I'll see you know, for sure!

How does TUV certification give any assurance that the box won't cause damage to the system, that's not what it covers.
The add on box will increase fuel pressure which could well damage the pump and cause over fuelling, it's how they work.

Dieselman, I wrote "If a product is TÜV certified and adopted by a number of franchised Mercedes-Benz dealers I am reasonably content to exercise my personal judgement".
Do you have a problem with that?

Not at all. Cuban expressed concern over the raising of the fuel pressure and your reply said
My point is that TUV certification doesn't offer any kind of product endorsement, nor does Mercedes Franchise dealers offering this as it will revoke any warranty offered by Mercedes-Benz and they are simply selling an item to make money on.
Which reputable engineering companies are you referring to that endorse this product and to what level.?
Of course you can use your judgement as you see fit.
Would I fit one to a CR fuel system? Not sure, it definately will shorten the life of the pump which are a bit fragile in the first place.

If the add on box increases the fuel pressure, how does the remap work?
I assume if it is a safer way of increasing performance it does not increase the fuel pressure? Perhaps increasing the time the injectors are supplying fuel?

I looked into remaps, plug in boxes for ages. I too was / possibly still are worried that the fuel pressure is increased. However from what I saw from the data on the laptop of the DTS box there are several digital parameters that they use to keep the pressure within a safe level. - They also set an absolute max level to which the pressure is allowed to increase to. This can't be past. I assume that the pump / injecters are perfectly safe at this level. There are about 8 settings in all, taken from a database, dependent on the diesel system / vehicle used. I'm probably going to go with the settings in the eco mode. More power, better mpg and obviously less overall pressure.
The type of box I didn't like the look of were the ones that either had user adjustable jumpers or variable switch to give more or less power. One box seemed to do all vehicles. You had to turn the screw up or down untill the smoke stopped !.
You could say the same about a remap that brings in the turbo earlier and adds more boost ? - is it safe or will the turbo blow
I guess time will tell

Plug-in boxes work simply by raising fuel pressure, you may assume that the box manufactures will set them at "a safe level", but by their very nature they "fool" the ECU into thinking that the requested pressure has not been reached. They run in an "open-loop", thats why they can smoke too much and damage particulate filters, no amount of screws, jumpers or feel good laptop adjustment can change that.
In the end its down to choice, if you are not worried about your emissions or injection systems then a plug-in device is for you. Im sure Mr.Bosch and your local MB dealer will be more than happy to supply the replacement parts if required

CUBAN do you work in the tuning industry?
Dieselman you have hit the nail on the head! TUV means nothing and dealers will sell anything to increase their margins. I wonder if SEAT, AUDI or PUG would use these devices on their race cars???

If that's all that's needed to tune an engine then I'm off to email someone in Austria....
Anyone got an addy of someone...anyone will do...
