I emailed them asking about their products for the W211 E55 and W203 C55.
For the N/A Engine they quote increased engine outputs of 399bhp and 398 lb/ft torque.
The E55 Kompressor engined AMG has 2 stages:
Stage 1 gives 518bhp & 537 lb/ft
Stage 2 gives 585bhp & 590 lb/ft

Has anyone used these guys?
Are they any good?
What are the "real world" improvements, as far as performance is concerned? And the improved 0-60 sprint and Vmax?

Many thanks in advance

Darren

Real world figures for the N/A are stock horsepower best case and less than stock worst, people will argue that they do improve them but these people have normally spent a lot of money on getting the ECU flashed.

I've dyno'd a few of these modded cars and i love to see the owners faces when they see the figures for the modified map and then the figures for the stock map, if you have the money burning a hole in your pocket then your welcome to send it to me, burn it or put it towards something like cams, headers or cats because they will give you an improvement especially the headers.

If your car is S/C'd like the E then they do have room to play with and these places do tend to be able to extract extra horsepower but its not like night and day so again i would say your best bet is to go for something mechanical and you have more options with the S/C than you do with an N/A unit.

Also if your car's are under warranty this will void it, if they are not under warranty then make sure you tell your dealer not to do any sort of update work on the ECU because the DAS will happy flash right over the modified map.

I agree exactly with Dan.

That said DMS do have a good reputation though - Autocar magazine have reviewed several DMS tuned cars which is rare - they almost never review tuner cars - and the loved them.

Remapping will always benefit turbocharged cars more than normally aspirated, and even supercharged.

If you want to spend some money and want to make a difference - go for mechanical changes, ie Limited Slip Differential, Headers, etc.

Only do a remap as your last modification, once the mechanical mods are done, as you may be able to fine tune the map to make best use of the other modifications.

Thats a good tip,,thank you,, I surpose its a bit like emptying you recycle bin after you have defragged

Exactly!

If your car is supercharged and you're thinking of spending upwards of £300 don't waste it on a chip, fit a pulley kit. It's a mechanical modification which has easily measured benefits! I suppose if you fall on hard times later you can sell the pulley kit, unlike the software tuning .

 

[GRAV888]

On the N/A 55, go for some 1/16" lift Billet cams and change the valves and springs etc.
Makes one hell of a difference.

Has anyone chipped the standard 113 308hp to get the 330 hp out of it, or any other ideas £400 seems expensive for that gain, OK i know the new engine has 388hp

Thanks mate.

I also tend to agree with the chip it last statement, if you can get more air into the cylinder's either by making it easier for the exhaust gas to escape or squeezing more fresh in then adding some fuel is an OK thing to do so long as you actually do it properly and see if your gaining anything from it (if your not then set the software back to stock - if it aint' broke don't fix it right), the problem is in this horsepower culture anybody will tell you more horses is good but when you ask how they intend to get that extra power it all gets a bit fuzzy.

If the majority of people had a basic understanding of an A/F ratio, half these chip 'tuning' companies would be out of work.

 

[stats007]

That said, there are many useful chip companies that know what they're doing and don't make wild claims. A slight increase in fuel economy and responsiveness is all you can really expect from a NA remap. The price of fuel nowadays it's worth it on a lazy V8. Some companies also offer a money-back guarantee to revert the map to stock if you don't notice any difference.

Ive have remapped a few of my previous cars, but ill talk about the 335d, and the difference was immense.

I didnt use DMS as i thought they where to quick to insult other outfits, and i dont like that style of sales.

I have used E-maps. Guy called Simon hes a nice bloke and knows his stuff, and a lot cheaper than DMS

My 335d was dynoed at 289bhp standard and 420lbft, and the car was pretty quick. After the remapp it was pushing 345bhp and 512lbft. and the car was ballistic it was easily a match for the C32 we had. It changed the car completley. That saying it was a twin turbo. . It also improved the economy by 3mpg. However even with its ballistic speed it sounded crap and now i drive a C55 and im in musical heaven

I havent had any experience in N/A remapps however ive asked simon about the C55 and he says it will improve the bhp from 367 to 387 and the torque from 510nm to 530 nm. He says upto 3mpg gain but can be as low as 1 but always a gain ( this is from asking all his customers) but itwill make the car much more responsive and better to drive.

I really have no reason to doubt him.....but i suppose ill be able to find out as its being done on the 7th may along with the ML he reckons 346bhp and 800nm and 3mpg better:bannana:

Ill report after a weeks driving and ill let you know

I've also had my 335D mapped and by DMS. I am very happy with the results. They are a very professional outfit and are one of the only companies to offer a warranty. They are also not as expensive as people think as they are happy to do a deal. As Steve said the difference can be very noticeable having a car re-mapped.

Last weekend I took the car to a rolling road to test the output, we had 2 E-maps mapped 335d's, and 2 DMS mapped cars and one stock. All of the mapped cars offered 40-50bhp more than standard but also there was no difference in output between the E-maps and DMS cars.

On the subject of dealers overwriting the map if that happens most companies (including DMS and E-maps) will remap it again free of charge.

Far a car like mine I'd go for the remap before any other mod to increase performance.

I normally use a chap that runs Power Engineering in Uxbridge. He does all the main companies, Superchips, Koch tuning etc.

The chap has been in the remap industry for 20 years+ and has worked with just about every remap company in the Uk at some point. As i know him very well over the years i took aka$h's E36 AMG down to him to see if he could work some magic on it. He point blank refused, in his own words "no signifcant advantage in power compared with the disadvantage in fuel consumption". He doesn't chip his own petrol n/a vehicles!

With regards to diesels there is a significant difference in torque. Yes fuel economy is better if you don't use the power. In all honesty i would reckon they're better on fuel at cruising speeds, but stop start traffic when you use the power is worse. Also when you floor the car the economy gauge goes down in large increments, ie 0.6 mpg drop compared to 0.1-0.2 mpg previously.

I know this as i have 2 identical vehicles here on my drive now, both the same year, similar miles and both just serviced. On local trip, one car following the other at sedate pace, the chipped vehicle was 0.8mpg better. On the way back at a brisk pace the non chipped vehicle was 2,5mpg better. I know its a crude way to test but none the less accurate in my opinion.

Also driving the vehicles back to back you feel the added torque during in gear acceleration, but driving the vehicles on a road the difference of 43bhp and 80nm of torque doesn't result in enough power to overtake the non chipped vehicle whilst accelerating.

Sorry to bring this back from the dead, but did you get it done and what did you think on the C55?

 

[DXB]

My 335d was mapped by DMS Also, now currently the fastest one in the country.

I actually pushed stevie A's C55AMG down the road on the way to a track day with him last year!

 

[BenzedUP]

DMS are way overpriced. I normally go for Engine remapping at West Tuning, tryed them about 4 times.. tryed and trusted for me!
